Well, here’s a candidate for nebulous question of the week. Haha.
There are probably as many answers to this as there are headphone users!
However your own stated criteria - comfort and quality of sound - should be your guide.
But I would also add another. Namely price!
As an example only: I bought a new HYPERX Cloud II gaming headset with removable mic and integral, in-line sound card for a mere £50 from ebay. These have all the bells and whistles you need, are of good quality and have proven to be comfortable with prolonged use.
So yes, comfort, quality and price.
Your only real problem then is the sheer plethora of choice.
Good luck.
