I love mine, a CF Carry-On. (not the X which is the one with the 'face' pocket)

Tumi has The Best ©®™ wheels and the CF wheels are 95% as good.

But what you're really looking for is something with a perimeter frame and latches. That is the real game changer. No more swinging a zipper around trying to avoid hitting the dirty wheels with your clothing lol.
The perimeter frame provides a rigidity that makes opening and closing the case simplicity and elegance in itself.

I have an earlier version, with the battery pack connection to the two external USB-A ports. Never used it because I didn't want to bother with fooling with the battery pack in security. Any battery pack could be used because it sits in the interior pocket. They just routed a USB wire from the interior pocket to the ports.
The earlier version also provided the option to emboss your initials in the top leather handle

Handle and rails is solid. Two nitpicks with the handle itself; it has 90 deg edges. So resting your palm on a corner soon digs in as you push it along, fortunately it's not too crazy, just enough to notice. The other one is that the bottom of the handle is also 90 deg corners, so pulling something off the rails will often hang up on the handle, requiring your second hand.

(Sold my Tumi because it was the smaller carry-on, Continental vs International or something stupid like that. Also it was zippered.)
