I had an iPhone 6 which i did like, but i switched to my S6 Edge, which is much better.
Although it depends which OS you prefer

i have always had an iphone, but after i shattered my iphone 6 i got a note 4, and i honestly would not be able to decide which one i like more. You should definitely try them out at the store before deciding. It will mainly just depend on your personal preference.

I had a android along time ago and thought it was a little more complex. But here lately in the past few years I have had IPhones and I find them very easy to use. And I like the sleek aluminum look to them. Not sure if the new androids have it I don't really keep up with android but that was a reason why I left android was because of the plastic. But thats just my opinion. Like the user said above me it mostly is just on your preference of OS and the style of phone you like. Hope this helped

love galaxys.
galaxy over an iphone any day.

I have the S6 and im not much of a fan of it. However I do think it has more and better features than the Iphone. I would still rather an Iphone just because of personal preference.

It depends what you want it for.

The UI for Apple is much more user friendly.

Samsung is more for developers and such. Also, people who want to "hack" games.

Tom has an iPhone. He uses that iPhone to make calls. Calls can be misinterpreted. Misinterpretation leads to anger. Anger leads to sadness. Both emotions lead to tiredness. When you are tired you get no work done. When you get no work done you need to sell your home. When you sell your home you lose everything in it. When you lose everything you have no TTG. Don't lose TTG and buy an s6 today.

Any day of the week.

I have always been an iphone guy but the gs6 edge looks dope and has a great display, idk it your choice bro

Samsung>LG>Apple

Samsung and LG are very close but Samsung just pull IMO. But apparently LG are bringing a G5 Pro next which will be amazing.
