first hand experience; S5 or ONE M8

So i'm finally biting the bullet and going back under contract. Anyone have experience with either of these phones?

I've got the One M8. It's a fine phone. I've been a fan of the multitasking on the HTC phones for a few years now. Pretty good battery life and size. This phone is almost too large IMO. It's also got a very sleek design that almost requires using a phone cover. It is slippery. Luckily it has some built in waterproofing that will let you get away with dunking it in water. The next/newest version of android is coming in February. IIRC the S5 has a better screen. That's all I know about it.

I have an S5. great phone. IR for controlling TVs and other electronic over finding a remote. i perfer samsungs PC Software, over HTC. S5 is waterproof like the M8. i find the aftermarket support is greater for the S5 over M8.

Also have the s5, no problems, great screen and camera and good battery life. I have no experience with the m8. I don't think you can go wrong with either though

I have an S5. It's a big improvement over my previous iPhone 5. The OLED screen is awesome to look at.

forgot about the S5 power saving, and Ultra power saving mode. makes the battery life amazing when low

I've had the One M8 since about the first week it was released. Battery life is great, and has a very premium feel. Despite some of the online reviews bashing the camera, I find it takes really, really good pics, especially in low light conditions. Either the M8 or the S5 is a good choice, IMHO, I just really liked the heft and feel of metal. Mine has survived 3 caseless drops onto pavement with only tiny dings, so it's tough too.

Decided to try out the S5 Sport in blue, because, why not. It won't get lost in the sea of black that most electronics are. Plus, I can always get a normal S5 for a restocking fee within the next 2 weeks.
