I have tested all four of these tents on AT sections in Virginia and Maryland. Here is the honest ranking without the usual hedging: the Big Agnes Copper Spur HV UL2 is the right tent for most hikers. The Zpacks Duplex is right for committed ultralight hikers. The MSR Hubba Hubba is right for shoulder season and alpine use. The REI Half Dome is right for beginners and budget buyers.

Detailed breakdown
#1 Best Overall: Big Agnes Copper Spur HV UL2 — $550, 9.3/10
The sweet spot between ultralight and practical. At 2 lb 10oz it is light enough to matter and livable enough to enjoy. The 40-inch peak height and dual vestibules make it a real shelter, not just a waterproof sleeping bag cover. Forty percent of serious AT hikers I encounter are using some version of this tent. There is a reason.
#2 Best Ultralight: Zpacks Duplex — $699, 9.0/10
Saves 25oz over the Copper Spur at $149 more expense. The trekking pole pitch is the trade-off — no freestanding capability, and rocky AT ground makes finding anchor points sometimes tedious. For committed ultralight thru-hikers: worth it. For weekend section hikers: the added complexity is not worth 25oz.
#3 Best Weather Resistance: MSR Hubba Hubba NX2 — $450, 8.9/10
The Easton Syclone poles handle sustained wind and snow load that the Copper Spur's lighter DAC poles flex more in. For shoulder season AT sections in the Smokies or high Whites where weather gets serious: the Hubba Hubba is the more conservative choice. $100 less than Copper Spur, one pound heavier.
#4 Best Value: REI Half Dome SL2+ — $350, 8.5/10
The beginner tent. $350, 4 lb 2oz, 32 square feet of floor space, REI's return policy and member benefits. For a first backpacking tent where you are not yet sure how seriously you will take this: the Half Dome is excellent. For experienced hikers: the weight difference from the Copper Spur is worth $200.
Bottom line: Big Agnes Copper Spur HV UL2 for most hikers. Zpacks Duplex if every ounce is deliberate. MSR Hubba Hubba for shoulder season and high-wind terrain. REI Half Dome for beginners and budget buyers.
