Re: Galaxy S5 vs moto X
Really it comes down to which you would prefer Screen Size wise, and Price Wise.
The Motorola X is an incredible phone still, and it's by no means outdated. Quick pricing online shows it is either free with upgrade, or very nearly free which compared to the $200 Galaxy S5 is very attractive.
You need to go to any carrier store and get both phones in your hands. Feel how each of the screen sizes feel in the hand, and compare the build qualities. That can really help your decision if you find the 5.1" Galaxy S5 too unwieldy or if you find you prefer the bigger size compared to the Motorola X.
Personally while it's a tough choice if my budget permits I'll likely get the Galaxy S5, or the HTC M8. While I do really like the appeal of the Motorola X, I'm a specs freak so I like having the latest and greatest even if it doesn't offer much improvements.
