I own, and love, several Fender basses. They work for ME and what I need them for.
If I were you I would get that ESP six days a week and twice on Sundays. The tone and style you are looking for are pointing to that bass. There's bonrule that says you're "supposed to get a Fender"..... especially in the metal community.
Get the gear that YOU will geek out over within your budget. The more you love your gear, the more excited you'll be every time you pick it up.
The goal is NOT to walk the line on anyone else's opinion of what you should do (including me). The goal is to keep playing, and for your music to make you happy. If you think to yourself "$%&! Yeah!!!" every time you pick up your bass, you've picked the right bass.
Short version: The Fender seems to be an "obligation" to you.... something you have to talk yourself out of or into. The ESP seems like the bass you really like, but are worried about how others will accept. Given the choice, go with the second scenario.... every.... single.... time.
(By the way, there's just something about a black-on-black bass that will always be BA.)
