Never driven a Suprima. I expect it's similar to a Preve. Never driven a stock E36 before. So I wont be able to tell also. Still .. Bimmers are known to have good handling what with their 50/50 weight distribution, all alu arms coupled with their solid build. Thus I am a bit suprised when someone says a Proton FWD beats a classic BMW RWD.Try driving both, then you'll know. But IMHO, Suprima engine, although it has enough power and potential to mod, is not worth it. It's not very reliable (oil cooler hose problem) and it's not smooth at all.
Also kinda odd that the one with the powerful cruise liner agrees.
