Brushless motors are also more efficient, and will produce longer range.
Wilderness kits have acceptable quality from my experience, but do not come out of the box nearly as customizable as Crystalyte, and you need to make / buy conversion wires to use the Crystalyte equipment. These are available from a couple of e-bike specialists out there.
Thus, it comes down to what you like. Hobbyists, customization fiends and those seeking lots of different high powered options will prefer Crystalyte. If you are content to enjoy your electric bicycle in a fairly standard configuration, Wilderness is just fine! It can also be adapted later on to use other controllers if you like, but its usually easiest and cheapest to just have what you need to begin with.
One of the things that makes Crystalyte so popular is that it is extremely versatile. Crystalyte motors will handle a wide range of voltages, there are many controllers and throttles to choose from, and accessories / secondary components are both numerous and continually improved.
For some examples of things available for Crystalyte and WE, Itselectric / Power in motion is an excellent resource. There is a lot of information available on their website, along with some more examples of related products:
I have personally dealt with Ken Cheung (the owner) of Power in motion quite regularly, as his bike shop is across the hall from mine, I own one of his conversion kits and batteries, and one of my tenants works for him. He's quite good on support, extremely knowledgeable, and innovating quite a bit on the product. He would be a good resource to go to for building a system.
