Ehhh. We all have our opinions and reasons for liking what we use. Let's not let this thread turn into yet another Apple vs Android argument, which are oh so common on other (biased) forums. Those "discussions" never get anywhere.

To chime in for the OP, I love playing on my Note 3, so you'll probably like gaming on the S5. I've not used an S5 in person, but I'm sure it's a good piece of equipment.
