I have a "Progressive Desk" frame with a third-party table top (which was much cheaper than what Progressive Desk offered). There's no wobble, and the table is very stable. The biggest benefit for me actually ended up being able to quickly adjust the table height while sitting down. I don't often stand in front of the desk. However, I do frequently adjust the table up and down a bit to change the angle my elbows are bent at so I have less or more support for my arms and shoulders. Before being able to do that, I used to suffer from occasional shoulder pain/stiffness.
