For a better grip on a "stubborn" fastener nut, it is better to use

a box-end wrench.


The word "pipe" in "pipe wrench" should eliminate "4" if common sense doesn't. Adjustable wrenches are sometimes hard to fit onto stubborn nuts and often slip so that's not a good choice. The same applies to open-end wrenches. On the other hand, a box-end wrench entirely surrounds the nut and fits snugly. So long as you've got the right size box-end wrench, it's unlikely to slip.
