Hi, i played tf2 for 3k hours, im a nerd as well .
If you want something serious for tryhard and are not sensitive to treble, the 1990s would be a good option for sound and comfort. On the other hand Sundara in my opinion are better in terms of sound for music, they are a good all-around but as you already have about 4xx I would probably go to Beyers.
You have a database / opinion here that may help you by @Falenkor.
