Not a fair comparison.

I have been a platform rider all my life but i finally caved and tried out clipless. I must say i did like it and I was faster, go figure. right now i have a cheap lender set of clipless pedals (shimano m520's) and im useing the multi-release cleats. I want to get a nicer set of pedals and i am will to spend so.....I have been looking at 2 options
1. CB mallet M's
2.shimano m-424, would get the m-545's but there heavy
i have already searched and have determined that there is no pedal that i can use as a clipless and as a platform. another words when i try new things and go big i use vans and plat's. I would like to not have to keep switching the pedals out but i guess that i just going to have to happen. so im trying to find out what people think about these pedals for clipless use only. i like the fact that with the spd multi cleat i can pop out in different directions and i have read that the CB is a heel kick-out only cleat system. also does haveing a bigger platform help when being clipped in and doing drops, jumps and climing?
The reason I say that is because that Mallet is a quality pedal, and the 424 is a cheap pedal. The only fair matchup would be between that Mallet and a 647, the newer generation Shimano DX platform clip. The resin cage on the 424 doesn't have a good retention system on the outside end of the spindle, so the first good whack on the end of the pedal dislodges the spindle cover cap and the disables the spring. And shortly after that the resin cage is wallowing around on the end of the spindle and then later comes off. I didn't have a lot of problem with the 424 on my Bullits because they have really tall BB heights. On my Nomad I went through 3 sets of 424s in just several rides. I switched to 647s...problem solved. Though the 647 also has a resin cage, it is a totally different material and attaches the end of the spindle in much more secure manner. You can also get parts for the 647. I notice that DH'ers who use Shimano clipless are using the 647 now.
On your question about how clipless platforms help...they do give more security in really rough terrain, and definitely yield way more power to the cranks for step ups and such. There is definitely a large preferential element to pedals, especially as it pertains to clipless or flats, and it may come down more to what riding you're doing. I think serious FR riding is probably better done on flats due to the unusual nature and hazard of the kinds of moves and actions being done on the bike. Bailing in more aggressive FR moves is common and certain hopping moves can be done better on flats. But this is the AM forum, so I'm guessing you're doing more trail than hardcore FR. If so, the clipless platform pedals provide more benefits than negatives. In technical terrain where you have to clip out to dab and where rocks and baby heads try to separate you from your pedals, the clipless platforms IMO are really superior to non-platform clip pedals. You can reacquire a clipless platform much better and that split second situation of not being able to clip in still allows you something to substantially put your feet on while you do reacquire the cleat.
Now, many riders are very capable of using non-platform clips and flats in all manner of conditions and do it well. I always contend that in a trail situation, and even in very aggressive, technical trail the clipless platforms are better overall for the reasons mentioned. But not everyone is wired the same. Many pro DH'ers for example use flats and many use clipless platforms, so go figure. The flats, clipless platforms, and non-platform clipless are all options for good reasons...people are different.
Both the Mallets and 647s are good pedals. My only concern with Mallets is that you cannot clip out on a CB pedal until you turn your shoe the required amount of degrees. It will not come out. The Shimanos allow you to tension the pedal retention device to your preference, so that even if you have one of those millisecond crashes with no time to prepare, you do come out of the pedals. Everything's a compromise. You just have to find what suits you.
