Strengths:    Brake power,
Good working with air bubbles: after I shortened the cable the brakes worked fine and bleeding was not necessary but I did it.

Weaknesses:    Bleeding is similar to avid elixirs - needs a lot of time to do it.
Some dot 4 fluid has better performance than original dot 5.1 - I immediately replaced the original oil to dot 4+.

Bottom Line:   
This brake has similar power to Shimano. I choose this bc of the 4 pistons / caliper but it seems does not matter. Shimano reached this power with 2pcs pistons / caliper...I think only the brake pads surface area does matter not pistons qty.
Modulation is great, I do not like shimano on-off brakes and its' designs so this brake is a very good alternative.
My previous brake was elixir CR and SL. Compared to this, Guide has almost double power but elixirs was not a great brake for AM. Modulation is similar or a little bit better, the difference is not big.
I have to get used to the shortened braking distance and I have to develop my arm's muscles to keep myself on the bike while I stopping.

Strengths:    Modulation
Smaller/Thin Levers like Shimano
Strong braking power
Do not take on air like older AVID models

Weaknesses:    Not as strong as Shimano XTR in power, but close
Lever reach adjustment is cheap plastic and sorta notchy to move - not as smooth moving as the XTR trail adjustment knob.

Bottom Line:   
I had XO trail on my 2014 S-Works Enduro 29ner. I replaced the XO master cylinder with the RSC master cylinder and kept the original 4 piston XO calipers since the same caliper is used. Easy upgrade since caliper and hydraulic lines are reused. I even reused the olives. I love the smaller thinner levers - just like shimano's XTRs but they do not have the dimples that the shimano levers have. The brakes strongest asset is modulation and they do not absorb air into the line like past Avid models. That alone once you try them is worth the money. They are strong but not as strong as the XTR in terms of power but very close. You notice the power difference only on very long down hills.

Strengths:    Lever feel, modulation, and adjustability. Gobs of power when needed, and most importantly, quiet. No, seriously, they're quiet.

Weaknesses:    Weight if any. The rotors aren't the lightest.

Bottom Line:   
Background: I have short fingers and large palms. I prefer my brakes with the levers in close, but quick engagement/bite point.

I've been messing around with Avid brakes for the last previous generations. Their Juicy line was pretty decent once you hit the 7's. Great modulation and lever feel/position, but "that" noise. With the addition of some Dangerboy levers, the Juicys just had a perfect fit. The hard braking noise was always persistent.

Skip to the Elixir line. Although I didn't have nearly any issues that many people have described, the Elixir 5's, CR's, and 9 Trails all worked well, when probably set up, bleed, and maintained. Avid has a perfect lever position IMO, with the Elixir included. But the brakes lacked in overall feel and adjustability. The CR's and 5's worked, but didn't have the bite point adjustability, and always had a built in amount of lever throw, which for a close lever, means nearly at the bars. On the flip side, the Trails worked fantastically with adjustments in bite point, but still gave a bit more lever throw then I would have liked, ironically enough. For all above brakes, there was still "that" noise though.

Now, the Guide RSC. Lever ergonomics reminds me of the replacement Dangerboy or Straitline levers, that one finger , just right sense. The lever feel is smooth and crisp, definitely helped by ball bearings. With adjustments of lever position and bite point, I've been able to get my levers set up just right for my hands: close lever, but quick engagement. Performance wise, these things are killer. Few of the "first ride" articles floating around point to more of a linear feel, which is pretty spot on. Shimano's tend to have a bit of a pop when pulling the lever due to their cam system, with a big amount of stopping coming almost instantly afterwords. The Guide's tend to pull smoothly, letting you feel when your pads made contact, then applying more pressure to slow you down in a hurry. This lever pull isn't mushy or overly soft feeling, but has a solid feel when the pads contact. Although they don't have the overall initial stopping power the Shimano's tend to have, the Guide's have that power on tap within the modulation. The modulation there is nearly limitless, letting me crawl down trails, lock the wheels up entirely, or just scrub the smallest amount of speed. And the power the Guide's have is impressive. I wouldn't suggest forgetting that they will throw you OTB in a loose gravel parking lot.

I'm giving this a new paragraph because it's worth it. These brakes are actually quiet. Yes, you heard it here, quiet. No turkey gobble, no running water; Quiet. My set up is as follows: SC 5010, RS Pike, 180mm rotors f/r, Sinster-metal. Yes, I'm using a noisier pad material, but these brakes are quiet. Initial set up had a bit of noise, but during break in it faded away a bit. Once bedded, and ridden, the noise disappear. It's made some noise on me, during very low speed stuff or getting some water on the rotors, but not the typical noise we know and love from Avid/Sram. I'm tossing up the low speed noise to metal pads. You get the same noise from a Shimano or other company under the same circumstances.

Jury's out on the durability and reliability, but after a few weeks of riding, they're fine. I don't even have any brake rub or anything (but hey, I'm a mechanic). I'd imagine they'll be quite fine for a while, but I'm arguing the initial set up is key. After messing with so many Elixirs, I took extra precautions and throughly bleed the brakes, as well as lubricated the pistons in the caliper. I take these precautions of most other manufactures as well, however.
