I've flown first class. Whether it counts as nicer or not probably depends a lot on your preferences. The actual service provided on a first class plane flight is definitely more classy. Everything in the plane is more likely to be in perfect repair, with no signs of wear and tear like you see on Amtrak's aging Superliners. And the flight attendants are more likely to give you "first-class" treatment than an Amtrak porter in small ways like more consistently using "ma'am" and "sir" when they talk to you. None of that is consequential to me, but I realize it's worth calling out because my rust belt sensibilities are maybe tuned a bit differently from others'. If you don't mind things being a bit less polished, though, a Roomette is physically more comfortable than a first-class seat in almost every way. It's quieter, you can get up and walk around as much as you want. You don't have to deal with airports and airport security. You can close your door and make a phone call without bothering anybody. You can close your door if you don't want to listen to your neighbor's conversation. You can close your door and watch a movie without headphones. There's an actual table so you can play a proper card game with your traveling partner. etc.
