Note 3.
A quick comparison of the two:

Basically Note 3 is slightly bigger, slightly heavier, slightly less MP camera, slightly less powerful CPU, and doesn't have IP67 rating, heart rate monitor or finger scanner.
Note 3 has more RAM (3gig to 2gig,) uses same screen resolution (1080p super amoled) and batteries seem to last about the same time (roughly 2 days with moderate use.)
I already have a Note 3 + Gear, so can't really think it would be much of an upgrade.
