I don't have experience with the Baku 1 person in the field, only the setup in the local REI store.
The biggest thing I noticed is how small the floor space actually is. It supposedly has the same footage as the MSR Hubba, but feels so much smaller. Almost coffin like. The strut on top is a little small and doesn't offer much head room. The 2nd door/window is a really nice feature though. But there are only two vents. Both at the head and foot, neither of which are at the top of the tent. So not much of the hot air will escape and vent like it should. There is also the reported problems with the Sierra Designs floors allowing water to pressure through and soaking you and your gear in prolonged exposure. This is of course just hear/say, but reported none the less.
For the same design (single wall, netting in the inside, but minus a second door/window)a Tarptent Rainbow is much more feasable, roomier and much lighter by over a pound! And for the exact same packaged weight you could get a double wall Hubba. Super venty with the mesh and/or try the optional fly/footprint open air option which is always nice! Plus, the Hubba has seemingly bombproof materials.
Just my two cents. I hope this helps.
