Kalih box switches currently hold the crown, afaik, with low stem wobble.
However, panda switches also have low wobble due to how tight the body is on the stem, but this causes higher friction. However, this also leads to stronger tactility when the body is used with a tactile stem.
With other switches, like alps based switches, wobble is actually your friend. If they limit the wobble on alps switches, it intensifies their propensity to bind. In this case, a low wobble alps switch would be a horrible experience. Similar goes with cherry, usually the lower the wobble, the more friction you feel.
However, with kailh box switches, the wobble is reduced due to the shape of the switch, and the tolerances between the box and the body. It really is a win win here.
