Action Surge (for 2 more d8+3 attacks once per short rest) > Evasion?????
Absolutely! How often are you copping a (dex save for half) per adventuring day anyway? It crops up like once or twice a level, and even then its only a reduction in damage. You already have good dex saves as is (and a great dex score) so youre likely copping half damage anyway. Its not removing nasty status effects.
Action surge is a 1/short rest extra [run or withdraw action for mobility, extra attack action for offense, extra dodge or hide action for defense]. Its one of the best abilities in the game.
Now you can [bonus action step of the wind] + move + [run with your action] 150' along the walls and use your action [via action surge] to punch someone in the face twice at the end of that movement.
It opens up a lot of options on a monk.
4 Superiority dice that at most give 1d8 damage and some kind of minor effect > than 3 more chances to stun opponents?????
Not better than - I said about equal to. The abilities picked were riposte, disarming strike, and precise strike. So you are getting free reaction attacks if your opponent misses, ensuring your stunning fists actually hit in the first place, and automatically disarming (and dealing extra damage to) your opponent. I place 4 superiority dice about equal in value to 3 Ki points.
