Their both cheap quality less than desirable rigs/brands. But they have both gotten alot better and offer replacement parts that are fairly easy to get now days. Exceed vs Redcat I would likely pick Redcat personally. The Monsoon has pretty good reviews and if your not too hard on it might last you a while.
BUT if you could save up another $100 you could get a FAR FAR FAR superior rig to them with and HPI that would dwarf them in quality and aftermarket support as well as performance.
