If I were to say my favorite I would say Minecraft.
I believe that Minecraft has a replayabilty win on this situation - especially because I heard the Terraria developers stopped developing. I play both (not too much, although MC is an exception) and when you get to the top in Terraria it's easy to do everything and it gets boring QUICKLY. Even if you start a new character, who wants to go through all of the work to get their awesome things back? Well, not me.
Minecraft on the other hand (especially because I have a server that has country-sized builds and large towns) basically lets you build 3d objects, and that doesn't get boring. There's a lot of mini-games you can come up with, and survival mode seems to be a replayable thing, unlike Terraria.
Both are great games, don't get me wrong, but I like MC better.
