At this point you're better off waiting.

Wait for the 8th generation iPhone

Buy iphone 5S. its just so annoying to wait so much for a new phone....just buy it now cause u want it now....its not like iphone 6 is gonna be released in 2 weeks

Wait, that's what I'm doing. It comes out in the end of September. If you end up not liking the 6 after the announcement, get a super cheap 5S. Be strong.

If you wanna save coin then wait for the 6 to come out, then get the 5s off-contract from a third party, it'll be about $350.

I think the 5S would be better, you'd get cheaper contracts with more value to it (like more Internet data and texts).

Don't get an S5. It has last years hardware in a new shell.

If you want Samsung, get the Note 4 that's coming out. But I'd wait for the iPhone.

$900 a year?

Why not get an unlocked iPhone + a plan like $30/month Unlimited text, calling and 1GB data.

My contract expires in September, just when the 6 is predicted to be released. Bought my 5 on release date 2 years ago

This is why i buy all my phones off-contract.
Sure you'll pay $600,$700,$800 outright, but in the long run it makes so much sense. Those contracts are basically Hire Purchase with insane interest rates.

At the end of the 2 years you'll have paid 2X the value of the phone.

Either phone would be a vast upgrade coming from the 4s, but the 6 literally comes out in 2 months [tentatively] so I'd recommend just waiting. And just the sheer thought of you potentially getting an S5 has me gagging.

Onestly I've nevver gotten a phone AS it came out. I would suggest going with the 5s. Because Apple isnt gonna drop the price anytime soon even after the 6 launches.

Whats wrong with last year's hardware? There's nothing wrong with getting an S5, or even as far back as an S3 (an S2 is a stretch but with a custom ROM its great). The hardware is still great and they still get updates.
I have the first Galaxy note and it works fine. (I havve a custom ROM running though.)

Don't get a Samsung. Those are trash. Wait for the 6.
