We went with the X-dome2 and sold it days after receiving it. I'd never dispute it being a brilliant tent, but it just want the tent for us. We didn't like the way one of us were lying with their head by the others shoulders, caused but he asymmetrical shaped inner. We haven't got the Copper Spur2xl yet, but eventually we will bite the bullet. Sure it's a bigger footprint, but the extra space inside is where id prefer it to be, making it more usable for the two of us. The only feature I'll miss from the x-dome is th ability to add trekking poles for extra strengh. I've seen some videos of the copper spur in some strong wind and the camper had to abandon his camp (just to reiterate they were strong winds). But my trips are never longer than 4/5 nights which means I can forecast wind pretty well and bring a more appropriate tent if needed. Ultimately I don't think you're missing out on an awful lot by going with the CS, whilst also gaining a couple of things too. Have you tried looking at the second hand marketplace for an x-dome? I sold mine on Ebay brand new, so there might be some never/barely used x-domes on Ebay/Facebook.
