All great instruments you are looking into.
The key, as @howard pointed out in an earlier post is to get out and try as much of these basses as you can, or keep in mind, if you order something, it may not be for you.
That is a good point when ordering an EBMM BFR (Ball Family Reserve), that they really hold value well, considering they are always limited to short runs of 100 or less, or slightly over 100, like 107 or 109, etc…
They almost always hold value.
G&L are great basses, but if they are not for you, then you will want to re-sell it, and it will probably be harder to move a G&L then an EBMM BFR, for what you paid, or close to what you pay for them.
Carvin will almost always be used instruments, which is great, cuz they will go for less then what you are looking into.
The exception is that you can still order a new Carvin from Keisel, as they still have the license for Carvin brand, so if you prefer the Carvin name and logo to the Keisel, you can still get a made to order bass. I am not sure I recommend this, unless you have played Carvin, and know it is for you, because you will pay as much, if not more then EBMM and G&L, and you will likely take at least a 50%, if not more, just walking out the shop door with it.
none of the basses you are thinking about are bad basses, and none of them are bad buys, but you just need to make sure they are the right bass for you.
I am not much of a Fender Fan boy, but I love basses Leo Fender designed.
I love and can enjoy playing most all Stingrays from the SBMM Ray4’s with the Jazz or SLO neck, and Ray34’s and EBMM Stingrays, Both with the larger necks.
I have enjoyed the limited time I have had to test out and play G&L (another Fender brand and design), and am confident that any basses from G&L, in the styles I like would satisfy me.
I can play and enjoy Fender P basses, Jazz basses and Jaguars, and probably others like Dimension, Jazz Masters, etc…, but I knot this because enough Stingrays (and Sterling by EBMM) and Fenders and even G&L have been passed thru my hands that I know.
I recommend getting as many of these brands and styles of basses in your hands prior to ordering.
The exception to me would be a EBMM BFR. not only could it be (if you end up loving it) a dream bass, it is also an investment, that could easily lead you to your dream bass if it is not it.
Hard to say for other basses, even Fender American products that are still kind of stagnant on the market, and still cater to a particular group of Fender die hards.
There is nothing wrong with Fender Die Hards, they are actually good, they know what they want and they go for it. No problems with that.
