2e has quickly become my favorite system to GM. Soooo much easier. I'm running some PFS scenarios and converted curse of Stradh. Will be starting quest for the frozen flame soon.

I GMed a game in 5e from level 1 to 7, fully homebrew. It burnt me out. I never knew if an encounter was going to be easy or deadly, things swing so much if you're not willing to do the math and think ten steps ahead.

I did some GMing for Pathfinder 1e. That's a system I prefer to play in, not GM. Ran curse of the Crimson Throne and the player power creep was making it super easy for my players. I had to modify a bunch to not make it a cakewalk for my little power gamers. Ended up essentially re-writing the last book. So pleased at how much easier 2e is.
