For me the adjustability has been worth even though I don’t stand all that often, because it allows me to dial in the height of the desk in addition to chair height to make the setup perfectly suited to me. Addition of high quality desk clamp VESA monitor arms (used HumanScale arms from office liquidators on eBay) takes this adjustability even further, making my desk very comfortable to work at for long periods. And yes, the frames on the nicer standing desks are very robust. The frame on my Fully desk is several mm thick enameled steel that will be good for the foreseeable future… even when/if the top gives out, I can just get some butcher block countertop or something similar cut at Home Depot and bolt it on and it’ll be as good as new.
