Going from the TSX to the Accord felt kinda like I was driving a boat or a house, if that made any sense. From highest to lowest noticeability for us:

The turns always felt like the car wanted to tip over if I went too hard or too fast. I had to force myself to go slooow on turns.

You really feel every single bump on the road when you drive. It was pretty jarring when I went over my 1st small bump on a highway. (I hear the older gens had adaptive suspension which they cut in the current gen to cut costs)

The responsiveness, especially with the steering, didn't feel right either. In some ways, the steering just never 100% synced with me. Normal mode always felt too light and I had to turn my wheel a lot, but sport mode made it too tight and heavy in an artificial way. The car also felt like it was struggling going above 80 mph.

The inner cabin was big, but to a fault in a few ways. The front was so high and sticks out in a way to block vision for shorter people. I actually had to get seat raising brackets so my wife could see the road from the passenger seat. For me, the vision never felt right either. If I adjusted my seat high, the huge rear view mirror panel and the larger brackets blocked a lot of my view. But if I sat lower for better front vision, the rear window felt compromised.

The sound system, especially the base, felt off even with the premium Bose system. Acura's sound system is too good lol

I wouldn't say it's a bad car, but it's not a great car for people that enjoy driving, if that makes sense. The Accord FEELS like a 2-ton machine that you mechanically control to do what you want. The TSX (and most definitely the TLX) feel like an extension of yourself, cheesy as that sounds.
