Just hit lvl 60 on my own, I need to unlock t4,

I need gear but don’t know if I need mythic prankster runs ? Or pit runs ? Either way, I have fg to spend

Prankster runs if you need mythic gear
If you’re looking for improved gear boss runs (duriel, etc) are the best way to go or bloodied bosses.
For levels pit runs for sure or if you can get in on bloodied infernal hordes those are the best

have mythic prankster runs if u need

Can run your through some boss lairs depending on the loot table you need,
You definitely need to grind some levels whether you have BIS or not.
Level glyphs needed for your build etc..
hmu if you haven’t found anyone yet to help you all around
