Its a bit of a tricky one bros.., although 50/50 helps you learn the fundamentals alot easier if you get straight into CS you dont really know any better and with enough wheel time you get used to your setup anyway. the driving style is totally different between the two, hence why alot of CS drifters find it hard to go back to 50/50.
Also CS is pretty easy to get into these days as bolt on kits are readily available online, where as in the old days it was all about grabbing parts from different chassis and modding to fit, its definately a big step up from 50/50 theres a bit more adjustment in regards to tweaking your suspension etc but alot more fun and rewarding once youve cracked it.
