Come on guys, I just want to know what is your opinion about that.
You'll have to excuse everyone for not taking your question more seriously. I know how important it is to get the best bass for every different genre and sub-genre of contemporary music, so I will do my best to give your question the consideration it truly deserves.
I imagine the ideal bass would more or less be the exact opposite of the best bass for metal. If you think for a little while about the two genres and what they are trying to accomplish musically I'm sure you'll agree.
So what bass is best for metal? This Ed Friedland video definitively answers that question:
Just watch that video, and then choose the bass that is most different from the one Ed recommends for metal, in terms of number of strings, pickup configuration, scale length, wood species, finish, etc.
Ed's advice is quite specific, so you shouldn't have any problem inverting his recommendations.
