I use to have a 1978 T210 that I took into the BC. I also own a 185. I was looking at the 210 because I was in Denver and felt I needed the turbo and was looking to go faster.
When I bought the 210, I also had narrowed my search to the 210 or the A36. Ultimately I decided the 210 because it had a better CG range.. With some evaluation of the A36s CG range I realized that it could easily get loaded too far aft and after playing around with some typical loads and the CG envelope for both aircraft, I decided the 210 was better for me. There is a reason they put the middle seats in backwards in the A36.
I also liked the high wing. Both for shade from the sun and for being able to look down at the ground.
I took my 210 into the Idaho & Utah back country and into a few BC strips in CO. My limits were 2500’ or so depending on terrain, elevation, temps, etc.. I could generally land shorter, but takeoffs became very uncomfortable on strips shorter than that. I did not have a stol kit on the 210. I did not operate near sea level really ever.. so I might feel comfortable in shorter strips at lower elevation.
The nose wheel was pretty much the limiting factor for rough strips and soft soil. It is a smaller tire and when you are light(Ie no ballast in the back) the nose wheel is hard to keep light even with the yoke buried in your lap.
Places that I felt comfortable going.. Moose creek 1U1, Johnson Creek 3U3, Upper Loon U72, Sulphuric Creek, Smiley Creek U87, La Garita Creek, Hidden Splendor and a few others. I have been to Stehekin 6S9 in the 185, and would have taken the 210 there, but never did.
At the end of the day, I sold the 210 because to get meaningful speed advantage you needed to be above 12,500 and I did not enjoy breathing bottled air. At 8000’ the 210 would true out at about 165knts and 17.5gph... my 185 will get 135 knts and 15.5gph.. in a 3 hour trip, it only saved me 35 min or so and that did not turn out to be worth the $ to me. And, I knew I would be back in AK flying floats, fat tires & ski’s, so the 185 was not going up for sale.
The 210 was more $ to operate.. retractable gear, mine had TKS deicing, o2 system, turbo charger, TSIO520 with a lower TBO, auto pilot, etc.. Every time I opened the cowl to change the oil, I would cringe thinking about the what it might cost if something deep in there were to break..
The things I loved.. no strut to look thru/around when looking down. The 210 cabin is wider than the 185(same as a 182 I think).. 89 gallons usable(wet wing).. super stable IFR platform, auto pilot, looking at the ground speed.. unfortunately when the gerund speed was high I could not see the ground very well..

It is a great plane, perhaps not as sexy on the ground as an A36, but it performed better than an A36 for my mission. If I were to move south again, I would seriously consider getting another 210.
