How does this tent compare with the MSR Hubba Hubba?

Both tents are stable, and strong. The Copper Spur is a lighter tent, and has equal living space and vestibules. Both tents are well ventilated for 3 season use. The Copper Spur has a tapered floor plan which makes it dirrectional. If two are sleeping in it you will want to put your heads at the wide end of the tent. If your campsite isn't perfectly level you will want to put the head end of tent on the uphill side. The tent also has a large vent on the head end of the tent that works best if it is placed facing into the wind. All those factors can make picking your tent location more difficult than it would be for the Hubba Hubba. The Hubba is a rectangular tent so there is no head or foot end, and it can be placed in either dirrection. The Hubba has a better waterproof coating on the floor, 5000mm vs. 1500mm. It isn't going to make that big of a difference, but it will be easier for water to work through the Copper Spur's floor than the Hubba Hubba. All of that being said the Copper Spur is a higher end ultralight tent, and great choice. The Hubba Hubba is not considered ultralight, but it is good tent too. If money isn't an issue you may also consider the MSR Carbon Reflex 2. It shares the same basic design as the Hubba Hubba, but is much lighter. It weighs about a half pound less than the Copper Spur, and is just as stable and spaciouse.

This tent has a tapered floor allowing you more upper body room where you need it most. The Hubba Hubba floor is rectangular so the head & foot dimensions are the same. On the plus side, you can use either end equally whereas with the Copper Spur there is a definite space difference between head & foot.

Your going to get a lighter tent, more mesh for venting and seeing the stars. And the sidewalls are morevertical giving you more usable space and space to sit up in.
