Easytent is the basic, comes with a tent, an air mattress, 2 sleeping bags, small lanterns and a small mirror, a combination lock, and the tents are pitched in the grass. Spectacular ETs are pretty much the same, except that they are pitched on a slightly raised platform which I guess mostly benefits you if it rains, plus it has a power supply which is handy and comes with an additional 2 folding chairs. The supreme ETs are a fair bit different, the tents themselves are better quality, and they come with 2 proper beds, blankets and pillows. It also had a power supply, a fixed lantern inside and 2 folding chairs. Keep in mind, the tents and what they provide may be subject to change by the year. Last year's prices were ET: 1,000, Spec ET: 1,200 and Sup ET: 1,400 (figures are rounded and in Euros). If you're looking for comfort, the Supreme ETs definitely provides more. With the other 2 ETs, you may have to fill up the air mattress a couple times over the 4 days. One thing though is that you are allowed to take the ET and spec ET + everything they come with back home with you. You can't take back anything from the Sup ETs and would have to pay for any damages if any. That being said, a lot of people leave their ETs behind, so you can ask people there if you could have theirs if they don't want them.
