I like both of them. The graphics on Defiance are pretty bad if you're not play on PC, but its pretty fun. Especially if you're a fan of the show, which is a great show by the way. Honestly, the weapon upgrade system in Defiance makes Destiny look like it was made for little kids. Warframe is a lot of fun to play. The only downside to Warframe is that it does start off really slow. You have to unlock a few things and figure out the mod and upgrade system before it gets interesting. That's my opinion though. Everyone has their own taste in video games so not everyone is going to like the same thing. I also like Destiny even though a lot of people hate it.
