Imagine a perfectly still 100% wobble free switch, it wouldn't move, because we've just described a solid chunk of plastic..
The only way any two pieces move/slide across each other is if there's SOME wobble..
Wobble is not a characteristic to be Minimized..
The angle of attack on the keytop is a set metric..
Which means all (Correctly designed) switches must wobble by approximately the same amount, because the tolerance takes that angle into account.
The only difference you may perceive for wobble, is really just New vs Worn-In..
There could be a poorly designed switch which wobble more or less.. but ultimately, Wobble is NOT a criteria you look for or guard against..
