Im looking for a new bar myself. Currently using a york chrome bar at home. Can’t recommend the brands i am looking at by experience because i haven’t touched them yet, but look at the Pendlay Nexgen bar. Bearings are best but they have a cheaper bushing bar too. Rogue has some good bars. I don’t like the chrome bars because they don’t feel secure on my back in heavy squats. My gym uses raw steel bars and they feel great in your hands and have a secure grip on you back.
My current bar has light knurling and it is made slicker by the chrome finish. Be cautious about getting aggressive knurling. I have used them and don’t like them, and it really isn’t necessary for a typical gym rat. I hear that some PL’s like it though, but I think the feel of a bar with a medium knurl. Better to try out an aggressive knurl before you buy it. if you can’t try out a bar with aggressive knurling, i would think long and hard about it.
Consider no center knurling if you do high pulls or other explosive lifts that can bring the center of the bar in contact with your body. Lots of people like center knurl for squats but a good raw steel bar will not slide off your shoulders with or without center knurling. I think a smooth center bar is more versatile.
My 2 cents.
