I quite like Acufine. I don't find it that coarse, but I don't shoot B&W in 35mm very much, and I like the tonality and sharpness I get with the films I use it with (TX, TXP, TXT, J&C 400, PL100). I find that it really only gets one honest stop with good shadow detail over box speed typically, so if you are not getting good results, you are probably trying to make it do more than it can.
I use it in a deep tank with the replenisher, so I always have it on hand ready to use at room temperature, and I like that convenience.
I did have a batch fail recently, but I traced that to exposure to high heat--we were on vacation and the building's cooling system went down for three days. Other than that, I've used it for years without difficulties.
