Generally speaking, I think turbos are the sh*t. I really do love the sound of turbo spool and blowoff valves and such when those sounds accompany an appropriate car, like a tuned Supra. But there are other times I don't like the sound of turbos. For instance, I dislike what they've done to some of the newer BMWs. The F10 M5 sounds boring in comparison to, say, the visceral E39 or the screaming E60. Also, the new M3/M4 actually sound f*cking gross, imo, and that's coming from someone who finds it very hard to dislike anything vehicle related. To me, a good example of turbocharging done right can be found in the McLaren 570S. It sounds really clean and exotic.
To stay relevant to the thread, I'd prefer to own an E92 335is over the equivalent generation M3. There's something very appealing to me about being able to kick most peoples' asses in a race while simultaneously denying them the opportunity to lay their excuses on an ///M badge. Plus, I'm slightly more of an I6 guy than a V8 guy, even though I love both.
