I fairly regularly (several times per year) land our A36 at a class B airport: mostly BWI, PIT, and DTW. They are often the most convenient airport to access something downtown (such as a sporting event via public transport or a shorter Uber ride). Even our older 182 could blend in reasonably well speed-wise [though it often meant flying at full cruise power through much of the approach to keep the speed up to 135-140 KTAS].
I love the A36TN. For a traveling over 300nm airplane, I don’t ever want a normally aspirated piston again. The next clear step better than an A36TN is 7-figures and burns Jet-A.
I have only a couple hours in an M20, so I can’t fairly compare it directly. A36 club seating is well-liked by the family. (Have owned it 9.5 years; wife has literally never sat up front.) Turbo and TKS well-liked by me. It’s not cheap, but it’s reasonably economical and fairly fast. 185 knots on 16-17 gph. Can climb 1000 fpm through 12-15K (but at 32-33 gph), which is nice for quickly getting above low-level bumps and out of the maelstrom of traffic.
Landing at a class bravo isn’t really anything special and some bravo airports are pretty small. It’s more about the airspace than the airport. Some bravo airports have heavy general aviation traffic. Others charge large landing fees.
And some airports aren’t technically “bravo” but the most common method of getting there involves transiting bravo airspace.
Boeing field, next to SeaTac (but not in class b airspace) was my favorite place to land, and home field for me. Not too busy, but enough real air traffic to make good practice.
My favorite times were landing shortly after the last flight of the Concord before it went to park at the flight museum and watching it taxi off the runway from overhead.
And another time being told to extend downwind and look out the window to see a Blue Angel buzz the tower.
The main reason someone flies a small single piston airplane anymore is to work towards their commercial rating. And practice in class B airspace is an important part of that.
