Here is a bit of information I have collected on the same journey for a 2 person lightweight (like to have a little elbow room)
MSR Hubba Hubba HP - 1.93kg - 2.7sqm - floor 40D10000rated -walls 20D 330Thread count 1000rated - 3.5 season, will take moderate snow
Exped Venus 2 UL - 2.4kg - 2.8sqm - floor 10000rated - walls 1500rated - 3 season
Mont Moondance II - 1.98kg - 2.66sqm - floor 10000rated - walls 2000rated - 3 season, will take moderate snow
Easton Hat Trick 2 - 2.08kg - 3.7sqm - floor 30D 5000rated - walls 20D 2000rated- 4 season (they say below the tree line) will take moderate snow, very airy mesh inner.
One Planet Goondie 30D - 2.1kg - 2.8sqm - floor 100D 5000rated - walls 30D 3000rated - 4 season, moderate snow, can save some weight with mesh inner also mesh inner and 15D outer lighter still but not sure how it would go with snow in this configuration.
Vaude Hogan UL - 1.8kg - ? - floor 40D 10000rated - walls 40D 3000rated - 3.5 season, moderate snow, very small vestibule but award winning tent at a very reasonable price.
There were a lot of other tents out their but these all fitted my bill of lightweght (who decides whats lightweight is a plce of great debate, for me under 2.5 kg as my mountain tents are all 3.5 kg plus.) Strong enough to survive multiple wet days and strong wind, have a strong enough floor that I don't have to carry a footprint and add extra weight.
There are many things to consider in your purchase, look at internal length and inner tent shape (steep walls) if you are over 180cm tall as a wet foot area in your sleeping bag is the result of not enough length and touching hard against the side walls. Is the vestibule big enough for your bacpack or just your boots. Do you want a full mesh inner, great for ventalation in summer but damn cold in the alpine regions in winter (won't ever have condensation problems though

) Be aware that the lighter the fly fabric the less UV resilient it is. Lots to think about, plenty of good reviews on youtube so you can see set up and get a sense of the tent you may or may not buy.
Out of my list I think the one planet Goondie is great tent overal,l weight + decent floor & walls + vestibul space, all ticks (also comes in 1 person vairables)
I decided on the Easton for the room, as it will be used as a 2 person tent all the time, it is very airy with all mesh inner and will definatley be cool when I go to north India in October.
If vestibul space isn't a priority check out the Vaude.
Plenty of other tents out there so happy shopping
