First of all I think you should reconsider your plan to replace your 2M Black. To wit, I am currently comparing two phono stages, C-J TEA 1 series 3 and C-J 88, both very expensive (well above those you are considering), and one of the cartridges I am leaning on heavily to do so is the 2M SE, which is the 2M mono based on the Black. My point is the 2M Black a very fine cartridge, well suited for use with any of the phono stages you are considering, and very near tops at it's price.
Next, are any of the units you are considering offered with return privileges? If so, I strongly recommend that you start with those. Given that all of the ones you mentioned have good reputations it really comes down to which one sounds best to you.
