From technology side Samsung is better, in facts many of the components used by apple to this day is made by Samsung, the same for from price side Samsung is cheaper.
But I don't have any of those, I buy from another company.
Which one? I have 15 days to return mine, if I find something better.
The Samsung S5 is head and shoulders above an iPhone for me with an expandable memory, removable battery and the 5.0 Lollipop OS upgrade. It also has a quad core processor which makes it lightening quick and is water proof ( I like walks on the beach). The S6 is more like an iPhone with a classier metal body and the S6 Edge has a beveled display which is way cool but is not expandable and cannot remove the battery, although the dual quad core makes that thing feel like a techno crotch rocket. It alkso stays with the 5.0 Lollipop OS.
I go for Samsung I like the S5
