There has never been more variety or options for a bassist, so it's a great time to have this choice to make but it can also be bewildering. That's a lot of money to spend on something you don't know whether you want or not. If it were me, I'd start with the basics:
What size neck do you like? Chunky or slim? Precision sized nut or Jazz sized nut? If it's not right for your hand, you're never going to love it no matter what it sounds like.
What kind of pickups do you like? P, P&J, J&J, J&MM, P&MM, MM, single coil soapbars or humbucking soapbars? Probably the most important consideration after neck size, in my opinion. You can change individual pickups but changing the type of pickup can require surgery.
Is weight an issue? If you're uncomfortable with a heavy bass, you need to rule out heavy basses straight away.
How many strings?
Active or passive? Again, a massively important consideration. Like pickups, this can be changed afterwards but you're better off getting it right first time.
Ergonomics - an extension of the neck consideration, I suppose, but do you need a forearm contour, for example?
It's fine lashing out brand names at you but you need to figure out what type of bass you actually want first and then start looking at the options within that kind of specification across the range of brands. Only you know what kind of neck you like. If you post examples of the kind of tone you like, it would be easier to make recommendations on how to get that kind of sound.
