I've never owned an IKEA desk, but can vouch for VIVO's frames - I'm typing this comment using a mechanical keyboard on an IKEA Karlby countertop mounted to a set of VIVO V120EB legs and am experiencing minimal wobble (minimal desktop wobble, no monitor wobble thanks to the gas-spring monitor arm I have).

I also have my desktop at ~49" off the ground, including castors and a 1.5" thick countertop, and I've read that no standing desk has 0 wobble at this close to maximum height.
