The moment I notice mine is early morning, before anyone else is up, with a coffee and a laptop and good light coming in sideways across the grain. A metal desk or a laminate one just sits there and does its job, which is fine, but a wooden desk has a surface that actually looks better the longer you sit at it. That's the whole appeal for me. It feels like furniture, not equipment.
When you're looking at one in person, or checking it the day it arrives, run your hand flat across the top and feel for any ridge where two pieces of wood meet, because that's where cheap ones give themselves away first. Open and close the drawers a few times. A good drawer slides smooth and stops with a bit of resistance, not a clatter. Check the legs are actually attached to the frame and not just to the tabletop with a few screws straight into the underside, which is how desks end up wobbling within a year. And look at the underside generally, that's where corners get cut because nobody's supposed to see it.
A wooden desk sits well against almost anything that isn't trying too hard. It looks right next to a plain upholstered chair, under a window with nothing but a lamp and a stack of books, against a wall with a few framed things hung low enough that you can see them while you're sitting down. It doesn't need a matching set around it. In fact it looks better when the rest of the room is a little mismatched, because the desk reads as the one solid thing in a room full of softer stuff.
What separates a desk you'll still like in ten years from one you'll be annoyed by in two comes down to joints and finish more than anything else. Dovetailed or mortise and tenon joints at the drawers and frame hold up to being opened and slammed for years. A finish that's been sanded between coats feels different under your palm than one that was sprayed on fast, you can tell within a few seconds of touching it. Solid wood will take a dent and still look like a desk with history. Veneer over particleboard takes a dent and starts peeling at the edge within a season.
If you've never owned a proper desk before, start with something plain and solid in a light wood, nothing with heavy stain or ornate legs, because a simple one works in almost any room you move it to next.
A wooden desk is one of the few pieces of furniture that gets more interesting to look at the more you use it.
