I have a Nallo 3 GT that I've used and abused in Colo, Wyo, and Alaska. I really like the design and roominess. The vestibule is fantastic for gear plus cooking. I've had mine in wind, rain, and fairly deep snow. You can't beat the steep walls which allow more useable floor space.
The Anjan is almost identical but is slightly lighter material and the fly doesn't go completely to the ground. The Anjan has better ventilation than the Nallo. The Nallo would likely be a bit better for areas with lots of rain and snow.
I use the fly alone and in situations where I want to go ultra-light and less bulk. I often bring along thin painters plastic for a floor. The fly used by itself is bomber=proof and has worked extremely well when I want a mobile, light camp setup. I've used it this way in Alaska as well as this year on a Colo bighorn hunt.
