I haven't lifted on DHS bars.
But, having lifted on Werksan and Eleiko and having multiple Pendlay bars (both bushing and needle bearing) at my gym, I would totally go for the Eleiko bars if you can swing the money. I honestly haven't lifted on Werksan bars enough to give an honest comparison to the Eleiko, but I would still go with Werksan over more Pendlay bars if you are going to spend the money.
I am very happy with my Pendlay bars, and I notice a huge difference between the bushing and bearing bars. So, if you are going with Pendlay again, then I say go with the bearing bars 100%.
But, I really want a men's and women's Eleiko bar for my gym. It's just not going to happen anytime soon.
