Iphone 5 vs Galaxy s5 vs nexus 5. Which one is better?

HI friends
I seen some android phone which one of this should i choose? I am confused what to buy. I know galaxy s5 has many features compare to iphone 5 and nexus 5. But nexus 5 has the fastest cpu. i like all but which one is best, I am not decided. Anyone who has expedience with this smartphones please suggest me for smartest phone in this?

thanks

Ultimately it goes all your budget but from the phone you mentioned, it appears money is no issue.. then I will simply say go for Samsung S5, this time it is more optimized device than a power house. For iphone 5, I won't suggest to for it as iPhone 6 launch is nearby, better to wait if you really want an iPhone.

HI Kalpi

HI friends
