'97-'99 Eclipse GS - RS?

Hey, sup everyone. I just wanted to know what are the differences between the Eclipse GS and the RS type, Im thinking about buying one soon, and need some advice on whats better. I was looking for a GSX but I just cant seem to find any in my area. So now im looking into the other ones (GS and RS) but i still dont know the differences in performance, if there're any. So if you guys could please let me know the differences between the two, and kind of lead me to a better deal.

Thanks in advance.

Why not a GS-T?

GSX-AWD 210hp
GS-T-FWS 210hp
GS-140
RS-140
