We have the Hartford XXL. I have to say I don't love it - it has pros and cons. Pros are: Quite easy to put up but you need someone fairly tall to lift up the centre at the beginning - you may need another adult's help at that point. Very light and spacious living area - great if you have to spend time inside in the rain, and also need space for wet gear. We liked the 4 separate pods in the XXL (think the XL has 3?)
BUT major con for us: The pods are really small - only just enough space for 2 airbeds squeezed in leaving no space for luggage, and the beds can only fit across the pod so one person has to climb over the other to get in/out. May not be an issue for you but a pain for us when getting up in the night for young children. Also the pods ceilings slope so one person's face is very near the lining - too claustrophobic for me. The pods are ok for kids but not big enough for 2 adults.
We had bad weather this summer and it coped ok but not brilliantly. We also struggle to get the SIG properly flat for some reason.
So overall I would give it a cautious recommendation with those various gripes.
