Well, my requirement is for weather-proof and water proof. beyond that, I'm an REI aficionado, so I biased. I like their line of 2-man tents, the half-dome gets it for me, but it's not a lightweight....no biggy for me.
On tents, my needs are spelled out thusly:
1 - room (2 person generally, but I need room to put in my pack and gear); 2 - durability, I don't like to have to constantly repair a tent for leaks; 3 - wind durability; 4 - ease of setup.
Just my thoughts.....notice that weight was not a factor. That is not entirely true, but anything in the 4 pound range for a solo or couples tent is fine by me. You will find that many of the light persuasion go for much lighter.
