I haven't flown a non-turbo'd 210, but was part owner of a T-210, bought new just as Cessna shut down the singles lines. Because we flew out of Laramie, we didn't even consider a non-turbo version.
We also had an earlier T-210 on the line when I was doing SE charter, although I was the official 182 pilot on that operation, so I didn't fly it much. The earlier models with gear doors had numerous maintenance problems, largely caused by the pilots extending the gear at the published 140 knots Vle, so we were required to get the speed down well below that before dropping the gear. Our line T-210 never had any substantial gear door problems because of that.
When Uvalde came out with the gear mod for older 210s after Cessna had already done away with the gear doors, that's when exhaust issues started occurring, as the mod didn't include sealing the wells as Cessna did. With the Cessna version, there is no exhaust problem.
Engine maintenance is an issue with turbo'd versions, especially if you are ham-handed with the throttle. The engine needs to be warm for the oil to adequately lube the turbo before spinning it up, and there needs to be adequate idle time before shutting down for the turbo to spin down. It spins at some ungodly speed like 20,000 rpm, and it'll toast quickly if it's not properly cared for. It's obviously a much more complicated system with the automatic waste gate, as well as higher cylinder pressures, so the TBO is shorter for a turbo'd engine than for a non-turbo'd but otherwise nearly identical version.
Overall, a 210 is a great airplane, very fast, heavy hauler, easy to fly (although very heavy taxiing), very stable, superb on instruments. If I were in the market, I'd be hard pressed to vote for a turbo unless I regularly planned to fly near the flight levels, as the turbo'd version doesn't give that much more normal altitude performance for the additional maintenance. I did a lot of high altitude flying on 02 (16,000, 17,000, once at FL230), mostly to say I'd done it rather than because of need, but that was when I was younger and foolisher.
