What appeals to you? Note is great if you want a large phone, one you can draw on. The M8 is a great general phone. G3 has the largest screen in terms of pixels. The S5 is only ok, the nicest thing about it is being water resistant. Moto X? Uhm, not sure.
I just picked up the Oneplus One. Read my review on this forum. Great phone, great no contract price.
