^ Smite has a much, much easier learning curve than Dota 2, that's for sure. I'm glad I started with Smite as my first MOBA. WASD controls are way easier to jump into than Dota's weird RTS-esque controls, especially if you're like me and you never played RTS games. And I've been saying this for nearly 2 years now — Dota 2 really needs to add a shorter game mode like Smite's Arena. Dota 2 matches can last up to an hour or more... casual players like me often do not have that kind of time to dedicate. Arena matches last like 15-20 mins, which is perfect. Any longer than that and I risk having to abandon due to real life stuff.
I say all that as a big fan of Dota 2 btw. It's probably the best MOBA out there, but Smite is superior in its treatment of casual players like me, so I play a lot more Smite than Dota 2.
