If I was playing I'd put it all into stamina, streamers I watch keep running out like instantly and still dying in one-two hits regardless of all those hearts.

at 8 orbs now so 1 heart, 1 stamina

hearts are more important for me at the moment so I don't get one shot D:

I have my Master Sword, and I am back to max Stamina, 3 hearts.

Upgraded armor and the item that you get after defeating Vah Ruta helps a lot - the moment when I stopped dying in the game and could focus more on exploration. 3 Upgrades for the stamina is enough for nearly everything for now. You can also trade health for stamina and vice versa for some rupees.

I was going  to alternate between the two as I progressed but so far only got one stamina upgrade and the rest hearts... trying to get to a certain number of hearts to complete a quest. 

I got to 5 hearts then started exploring, now I'm just filling up my 2nd stamina ring before going back to hearts.

I would like to put all in stamina but then I heard about the master sword. Now it's grinding to 13 and then back to all stamina again.

That's how I handled it. I got the Master Sword yesterday and have about 8 orbs currently that I plan on sinking into stamina. I already got to one of the furthest locations you really need to glide to, although a bit more stamina will help with Eventide Island since dying during its challenge deports you back to the last piece of solid land you touched way away from the island's coastline. Otherwise, being on my feet as much as I have been as helped find some more sneakily hidden shrines.
