Deadeye in my case, but I guess it will depend on how you play

They are all super easy. For health just use a bow to kill a bunch of people. And dead eye is laughable as well. 

Or fish for health, each catch was +20 to health.

Deadeye just play pvp and you’ll get it within a day or two, for health take a bow and mass murder cops on saint denis, you’ll max in a few hours 

I've been rerolling characters for a couple of days to get one that looks solid, and I'm trying to figure which of the Attributes to dump the free points in. Stamina is laughably easy to level up to max, but which one takes longer to grind: Health, or Deadeye?

Which of the Online Attributes is the hardest to level up?
