No, it is much nicer than the 737/A320 class. Just thinking of the curve of a 737 makes my neck knot up. Bigger planes like the 747/757/767/777 are much more comfortable as well as modern planes like the A220/E195. 737 class planes are so ubiquitous that many passengers have no idea another experience is possible.
I’ve flown on a wide variety of planes, and never found any difference in comfort from the plane itself. It’s all about the seats.
My dislike for widebody airliners is that the odds of getting a window seat are much smaller.
What’s even the point of flying if you can’t look at the world from up high?
