i think they are all extremely useful

Obviously VPIP and PFR are essential.

Went to showdown and folds cbet are good for seeing who are bluffable and who aren't.

The blind steal% lets you know who respect position and who doesn't, and allows you to reraise a lot more for greater EV.

The cbet stat allows you to make flop calls with middle pairs against people who cbet too much.

The aggression factors are great for calling bluffs post flop.
