You can't really go wrong with the series 3. If you drop down to the Jazz, at that price point there are many other options available. I don't have any personal experience with them but the Series 3 pretty much sets the high standard.
Personally I have a Tepui Autana Ruggedized. Approx the same size overall but has a covered entrance and annex. (I'm a Tepui dealer)
I'll offer my thoughts without pushing one brand over another. I don't use my annex a whole lot. It's a little cumbersome to set up solo at my vehicle height. So for just one night at any given spot I generally roll without it. However the covered entrance offers more shade or rain protection below it. Obviously also covers the ladder in bad weather. The tent is plenty comportable for 2 people. With 3 think backpacking tent quarters. The annex offers plenty of room for additional people and we have a cot for my son to use down there. An annex also gives to a place out of the weather for a portable toliet or the privacy a significant other often appreciates to get dressed. Dry place for dogs if you need it.
If you have any specific questions to the Tepui line I'd be happy to help out.
Not a great pic but shows most of the points I brought up. Here just camped for a single night I only used the one side window and the door for ventilation.(It was cold). You can see the additional coverage. Eezi-awn offers this style too.
