My thoughts and remember YMMV:
Speed Solution FF:
Slightly narrow - I couldn't break them in comfortably enough, and that's even with a shoe stretcher. Wound up giving them to a teammate.
Very comfortable cushioning
Lightweight and speedy
Court FF2:
Mono sock design really locks your foot into the shoe some people say they have a difficult time getting these on, but they're def easier than the previous version, that being said I don't really have a problem.
Bit more room; you'll see some people recommend going down a size, but I stayed true to my size. Half size down was too snug for me.
Extremely comfortable cushioning but with slight slight break in. Took me about <2 hours to break these in.
More mid foot stability
Weighs more but you really don't feel the weight
Expensive
