While it does look nice, I can't find anything that says they are legit. Only 3 youtubers have uploaded videos on them (which could all easily be from them), as well as the fact that if they have created over 1 million minecraft servers, you would think there would be more results about them. Also, on one of their youtube videos, it was nothing but complaining on how they couldn't do something which tells me they probably aren't easy to contact if something goes wrong. Along with the fact they don't have a FAQ/About Us/Contact page really makes me worried. They probably won't be picked for the said reasons.
Although they don't have forge, I was actually considering these two:
https://www.bisecthosting.com/minecraft.php - The one I was using before. Pretty stable, but rather dated UI for the admin tools.
https://mcprohosting.com/ - They are extremely well known, and they have DDR4 RAM which is the newest version whereas the one you listed claimed to have only DDR3. Although a bit pricier than the other, after looking at the FAQ page, I feel most confident about this choice. After you enter your username, you can view the modpacks they have to offer (ex. Bukkit, Vanilla, etc.)
Personally, I like the second one quite a bit due to their nice and clean site, DDR4 RAM, and that they were listed first on this hosting list: http://www.enjin.com/game-hosts
