Choosing the right knurling on a barbell requires some important considerations. You want to think about the type of lifting you want to do. For instance, a powerlifter may value knurling in a mountain pattern since it’ll provide the most grip on heavy lifts.  Then, try to buy bars from brands with good quality standards. Rogue Echo barbells, Rogue Ohio bars, or Texas bars are all good options to help you optimize your lifting setup. The Ohio Bar from Rogue is one of my personal favorites.
