I'm big and tall (6'5") and this tent was perfect for me. I slept on one side of the tent, my gear went on the other side. I'd say it's a "one me" tent as I don't see anyone else comfortably sharing the space, but I did have room to store my buddies' packs at night.
I was a little worried about the carbon fiber cross pole based on what others had said but had no issues. I even stepped on it once.
I never used the fly as rain wasn't a concern and man, this tent has the best "you're not in a tent" feel ever. It was great to wake up in the middle of the night, water a tree, and then lay back down gazing up at the Milky Way.
Buy the footprint (http://www.backcountry.com/stoic-arx-2-xl-footprint), it doesn't come with it, and then ziptie the footprint to the tent for supereasy setup/breakdown.
I packed the poles in a side pocket and used a smaller compression sack than the one that comes with the tent, saving a decent bit of room.
I'd recommend this tent to anyone under 6'6". Much taller and you're going to be sleeping diagonally.
