Depends. Mech games are a pretty wide genre. Battletech is simple but okay. Mechwarrior is kinda bad unless you mod them.
Mechabellum is a fun autobattler.
Into the breach is a good puzzle game
Daemon X Machina are both mid, but I've played worse so eeeeeeeh.
Brigador is a classic twin stick shooter esque game
Synduality was fun but the game is dead
Project nimbus looks like mechs but is secretly Ace Combat
Megabyte punch is single player smash bros.
