What can I say - I spend about 30 weeks of the year out in the field and most of that is in a tent or shelter.
My own personal choice is the Mega Light; I have had one for 5 years now and I love it!!!
I use it for sea kayaking, hiking, even in the snow - it works dang well and it is so adaptable to so many situations.
It is quick and easy to pitch, roomy (for 2 people anyway, might be tight with 4 considering the angle of the sides) and handles all sort of conditions - with the footprint it is a blessing.
The only thing is in high winds it acts as a sail (it has only collapsed twice on me) and the bugs get in (don't have the bug shelter), other wise it is my choice due to it's light weight, funky colour and ease of use as my personal shelter and emergency shelter.
You can not go wrong!
