Had the S3, and the S5 and loved them both - got an iPhone 5 with work and i just dont like the whole apple ecosystem. We get 20% off with work on phone contracts s o i ended up paying less for this one! Hopefully it's as good as it's been hyped!
I am a big nexus fan! Currently using the 6P and I love it. However when I had my S3 I had endless problems (Most likely a faulty device) But for me I am a big fan of stock android so Samsung is not for me!
