He's classing-up, Adam.
That joke aside, I'll look forward to reading the responses.
I have significant A36 (and of course, V35A, F33 and C33) time, and an adequate measure of 210 time, and I have a lot of respect for the 210. In the 210, you sit up all tall like an old Packard; in the Bo, you're more sports-car low-slung. In the 210, you ride in the shade, and unload out of the rain; in the Bo you... don't.
In the pattern, in a Bo, you can better see where you are going, but in the 210, you can lean forward and see what you need to see, so that is not such a big deal.
CG is a simpler task in the 210; it is tolerably close to the classic, "if it fits, it's in CG" model, while the Bo (yes, even the A36 to a limited degree) bears more scrutiny of aft loading.
The 210 is heavy on the controls, while the Bo is lighter and more responsive... which means, in IMC, the 210 is a lot less fussy.
Bonanza gear is robust and relatively maintenance free... the 210's... is not nearly so bad as some claim, but is definitely not up to the same standard.
Anecdotally, the Bonanza's a bit faster (for a given flight regime), but I do not possess hard numbers for that, so do not flame me. When I fly trips in tandem with my T210 buddy, I always slow it down a bit; I know that, if he needed or chose to fly higher, I'd be left far behind.
Third row of seats in an A36 are real seats, while in a 210 they are more like child seats, but neither plane works out to being a six robust adults and gear anbd fuel ride, anyway. 210 has much more flexible baggage-loading space, but the Bo has the big, honkin' double doors for loading. Of course, the pilot-side door on the Bonanza is single use only, and involves the use of cutting tools to open.
And that's about all I have to say about that.
