I've had both and still run an E30. The E30 is probably more up your street i would imagine. Setup to oversteer from the factory, stright 6 engine and imho a lovely shape.

You'll probably pick up a better 190e than e30 so take care if you look at them, really you should take someone that knows the cars with you.

Avoid the sports theres no difference in engine/power output - instead use the money you saved on getting a normal one to upgrade the suspension/LSD etc. There are always sports being stripped and a host of aftermarket upgrades available.
