Depends on what you want to spend. The Kyosho is a top dollar luxury ride. It's plush, quiet, smooth, and it gets the job done in style. The AE is the $18k pocket rocket (think Civic). Not as refined, or posh, but every bit as capable of getting from point A to B. It's going to rattle, make a bunch of noise, might even smell a bit, but it just works.
Is the extra $150, and having to worry about parts support something you're interested in doing? If so, RB6. If you just want to fill her up, and go, B4.

I run with 4. Only 1 has broken a rack since the RB6 debut. Arms, and rear suspension holders, yes, but no racks (yet).
