Highly subjective thing, so everyone has an opinion of course.
I've typicly used office store specials over the years...mostly because I havent ended up at a location nevermind home that I dont ever plan on leaving for a very long time, so between moving itself as well as different style of desk working or fitting better in a new place, it's just easier that way. Once I'm in a place and home I feel will be really permanent, then I'd go for a propper real desk vs the cheap particle board.

That said, I have 2 right now....one I guess you would call a medium sized desk with hutch, no corner or L or anyting...and the other is a big executive type desk. One thing I HAVE noticed with that sort of stuff lately is the veneer/laminate might not be what it used to be. The one with the hutch has the plasticky solid veneer that holds up well, even to moisture, with the only real worry is the particle board sagging over time (which I doubt will happen with this particular one due to the design. There isnt a big enough unsupported surface even if extreme weight was kept on it). The executive style one on the other hand seems to have a FAR inferior coating rather then a veneer layer, and does easily scratch and is very prone to moisture. In fact I had a glass on it for a whole 10mins maybe once before, and the condensation from it blemished the finish. I hope they arent all starting to be made like that.
I do like the executive style desks though...they usually have a much larger actual desktop surface for plenty of room to work...looks a lot cleaner...and can handle about any computer setup you want to throw on there. Like say you want to run dual monitors or something, you can easily do that while a lot of the hutched desks wont allow it. Also easier to keep the keyboard, monitors, speakers, etc centered up in ideal positions. For printers, routers, modems, etc sort of stuff if you keep them at the desk, I like to use a matching office cart made for such stuff, small bookshelf assembly, or even a kitchen/microwave cart.
