The only thing the Dell has going for it over the XDR is the camera/speakers - neither of which I use. Text clarity is equal. But in all other ways the XDR is superior. Money aside, I'd 100% rather have the XDR. That's not to say the Dell is a bad option. But it's like comparing a Toyota to a Porsche.
do you think the XDR’s panel is any better than the Dell’s? I’ve developed eye strain since getting the Dell, whereas I didn’t with my prior 27” 5K glossy display. Could totally be coincidence — the text on the Dell 6k is super clear as you mention (I’m running it at the recommended resolution). Wondering if it could be the matte coating.
So now I’m thinking about getting the XDR. $6K with stand is a lot to stomach, tho. You mention Toyota vs Porsche… I think I’d say entry Lexus versus top-end Ferrari.
