I have the grip n pull also. It does ok. You need good hand strength to use it. I have some lightly crimped ammo that it just slips off of even with adequate gripping surface on the bullet.
I seldom pull bullets, but use an inertia puller , never tried one of the others, never had to pull enough bullets to make it worthwhile to try one
I've been good till last night, loaded 20 rounds that was suppose to have 59 grains of powder but i loaded 52.5 due to me not paying close attention to my notes I have a inertia type and did a few.
I've been using the rcbs collet system. It's worked great for me. Downside is purchasing all the different collet sizes you will need.
Got a hornady collet puller, I will be throwing the inertia hammer away. Pulled all with no trouble, didn't scar bullets, very simple and fast, can have it pulled and done before you can get the hammer loaded and make a single blow. I see no benefit for the inertia over it other than the collet purchases
