What things do you do on your 2nd screen when playing?

I know of MechWarrior Online but doesn't it have annoying P2W cash shop crap littered all over it? Much like World of Tanks and their cousins?

If you want a mechbay packed with a huge amount of mechs to choose from the fastest way would be to open your wallet. However it's entirely playable without it. They also frequently do event things where playing the game enough will get you limited edition event mech variants that usually have a customized stock loadout and paintjob.

As for the pay to win. I really don't recall anything other than cosmetics and cockpit decorations being locked behind a pay wall and even then it wasn't all of them. Honestly i'd say the difference between wallet and free is basically the difference between instant coffee and hand brewed coffee starting from beans. One gets you what you want immediately, the other takes time but will likely result in a better experience.
