Thought I'd offer some feedback since we finally rode Sugar this weekend.
I found Sugar a lot more approachable for different riders. My wife has a bit of riding experience, but she's been on and off the bike for long periods of time, she found herself a lot more confident at Sugar than at Beech. I think the width of the trails was part of it, but also that the green felt a bit better laid out than the green at Beech, in addition to being longer. I think the green at Sugar is more wide open, with more line choices, and is generally faster than the green at Beech is, but the berms and rollers are really well spaced out and there are a ton of them.
I rode all of the blues also and I think they were a bit more approachable than the blues at Beech, the main difference being the width. The blues at Sugar were a bit narrower and tighter, but smoother and slower than the blues at Beech. In particular, the tech blues at Sugar were easier to ride blind and more approachable than the former Blue Ridge Rocks (Copperhead now, IIRC?), which strikes me as being closer to black. I'm always up for a challenge, but I was able to take my wife down the blues at Sugar and, while she walked a fair bit, none of it was over the top and it felt like a nice progression from the green and between what I saw of the blacks there. The alt lines give you things to work up to, but for folks transitioning from the green, there were other lines to push yourself on too without being overly committed. It feels to me, in comparison, that the blues at Beech are a fairly considerable step up from the green in terms of difficulty and commitment. To be clear, my wife being able to ride everything isn't the standard, rather that you can take someone from a trail and move up in difficulty, with it feeling like a challenge and an incremental change in difficulty, but not so much so that it feels like a drastic step up in skills required or confidence. I felt this progression is a bit more gradual at Sugar than at Beech.
I didn't get to spend a ton of time on the blacks thanks to a cracked frame. The rock roll looks way scarier in person than the photos I saw, but I don't have a ton of time on slabs, otherwise I think I'd have been fine on it.
In all, I think the trails at Sugar were lower commitment unless you took alternate lines and I think that the progression from green up through black is fairly consistent for people to work up towards. The progression at Beech from green through black is fairly considerable, IMO, even going from green to blue is a pretty big leap.
On the other areas, the lift at Sugar is much faster and more accessible than the one at Beech. It really moves quick! It's nice that it's two speeds, as well, so it slows near the bottom. That said, no food on the mountain is a really bizarre decision, as is the lack of a brewery or other amenities like at Beech. It also seems to me that Beech would drain better, it was a dry day and there were a few pretty persistent wet spots at Sugar, along with some low laying roots that look like they'd get real slippery.
Personally, I think people less familiar with park riding would find themselves more confident and enjoy Sugar more. Advanced riders would probably be fine at either and the enjoyment level is probably the same. I'd definitely go to Beech if rain was in the forecast, both because of the trails and because there is more to do on the mountain than Sugar when you aren't riding.
I will add that, if anyone from Sugar is listening, they really need to get some better footage of the trails. I talked to a few other folks who passed on riding at Sugar because the available footage looked 'dull' and 'boring'. I think having someone do some professional editing of chest cam or follow cam footage would go a long way in dispelling that. I guess they were working on it, because ski patrol was out with cameras, although I regret my one potential moment of glory was wrecked by my confusion as to what was going on and the placement of a hip jump that, I'll be honest, I'd probably send into a tree.
