Welcome to the forum.
I don’t have any recommendations, but what I would do is go to several specialist office furniture suppliers and have a look at what is available.
Make sure you measure your available space before-hand to be certain the desk you select will fit in!
If it was me, I would be sitting on the tables and wobbling to see how solid they are.with a weight on them. After all, you will have four monitors, two laptops, possibly a printer, folders, etc. on the tabletop. See how smooth the up/down movement is. How stable is it at the apex of it’s elevataion? Are there holes and ducts for all the power etc. cables? Ask how long the factory warranty is. I would want a fairly long one as adjustable desks are not cheap and you are likely to keep it for quite a while.
The place I bought my office chair from let me borrow a sample of the chair I thought best free of charge for a week to test it out. (They delivered and collected it.) They also offered to exchange my chair after it was delivered for another if I wasn’t happy with it. These are the sort of things I would be looking for from a supplier. Then you can test out your prefered desk before you buy it to make sure it works for you.
