It's pretty hard to give you the advice that I'm about to give because I don't know where you're from (fill out your profile). I'm saying this because the best way to figure out which bass is better is to try out both basses.
I have only tried out Eberle basses at Ideal Music(
http://bassesonline.com/).
Going from that experience alone, I have to say that comparing even two Eberle's is like comparing apples and oranges not just because of no two basses are alike. All of these basses are old stock from one time or another, so some might look completely different than others and even sound completely different.
The fact is, there was one really good Eberle and a bunch of not so good Eberles, but I could only tell because I was there trying them out. There is no other way that you can pick out a bass, really.
I have not tried out the Golliuhur Kremona-Bulgaria basses, but I hear that they are nice. The only true way to find the bass you really want is to try as many basses as possible.
I imagine that the Gollihur basses are not setup. Neither are the Eberles, well, sort of. Ideal has a bass player who plays the part of bass luthier, but he is definitely not a true bass luthier. The basses are playable, but nowhere near top notch playable. So either way, you'll be spending a little more money getting your bass setup by a good luthier, but it will be well worth it.
