I'm very limited in my closed back experience as I found what works for me. In my experience, I've tried:

Beats Pro: with a little bit of bass tightening and darkening of the upper mids, it has a really nice crunch. It's like using WF-1000XM3s but as a headphone. I've tried many other Beats, but this is one of the only two I'll ever positively talk about.

Sony WH-1000XM4: I actually regret owning them. It's almost as bad as Beats studios in sound, but with better tech and repairability.

DT 770s: hated them at first, but with new pads, I really love it's midrange and soundstage. I can tolerate the treble and the dips it has. EQ'd to Harman doesn't take much away from their sound and is honestly the best I've heard under $200 (which is what they cost new nowadays).

Sony MDR-XB500: for cheap little bass cans you can buy today, they are amazing. Unlike the Beats Pro, they're wide-ish sounding and I can listen to most of my library in them if that's all I have at the moment.

AKG K361/371: They're usable. Pretty decent sounding, tuning is mainly what separates them. They just don't sound as clean to me as the dt770s.

AKG K44: for $10, I got my money's worth. EQ'd to Harman, they sound usable but with zero bass extension. Naturally, it's the most interesting tuning I've ever had the pleasure of hearing.

AKG N90Q: there were several listings sub $300 around the time I got them and at that price point, it's amazing. Strong bass with no shelf or rolloff, while sounding smooth going midrange and even into its treble. It has an amazing soundstage and imaging to back it up for a pair of closed backs. There's also the other cool tech stuff to it, but at its core it's highly enjoyable for me, on top of having noise cancelling. At the moment, it's the best I've heard yet for closed backs.
