They are completely different tent. One is single wall without vestibule, one is double wall tent with vestibule. One is heavy as well, but bomber. The other is light and pretty bomber. Get the one for your intended usage.
This thread reminds me of one of my favorite hobbies: reading reviews from people who didn't read the product description. The EV2 is designed for fast and light alpinism at above 14,000 feet. If your intended application is literally anything other than that usage, it will not be a good tent for you.
