What are you going to use the tent for? Backpacking? Car camping? What weather? Any winter camping? Do you need to be able to stand in it? Is it really for four people? Just four people, or 4 plus their gear inside?
I have a Cabelas 6 person dome that is heavy. But I love it when all four of us go camping from the car. It will withstand torrential rains and has room to stand, plus all our gear can go in it.
But I have a 5 man tent made by Alps Mountaineering. It has two doors and two decent sized vestibules. It is light enough to backpack. Cool in the winter since it has LOTS of mesh. But cool in the winter for the same reason. It is very similar in design to a Eureka Apex 4XT.
I have never felt a tent that is labeled as a 4 man tent, can really sleep 4.
I guess to give a good answer, we would need more specifics about how you really intend to use it.
