Analysis:
Giant is 3x7, Raleigh and GT are 3x8 +GT & Raleigh, -Giant
All three have the Suntour XCT fork, GT has lockout +GT
All three have Suntour XCT crankset tie
Talus has Acera rear derailleur, Giant has SRAM X.3, GT has Alivio. +GT
All three have Tektro brakes tie
Giant has Kenda SB8 tires, GT has Maxxis Mobster, Talus has bo-bo no-names. SB8s are the absolute best for dry hardpack, Mobsters look better for wet & mud, don't know anything about the tires on the Talus.
I'd sit on each of them, see which one feels better. If it came down to the Giant vs the Raleigh, and they fit the same, I'd probably go Raleigh on the 8-speed, or else compare how the bike shop treats you. Other components are comparable.
The GT seems to be a little bit better equipped, but if dealing with Performance Bikes is a deal-breaker, then I'd go Talus.
