What Pickups should i buy?

[Klainti]

I have a Yamaha 4 string pj bass with 65-130 string on it and setup for C standart tuning, considering its price(180eu used) it plays very nice and the only thing it falls behind is the sound.
I use only the neck pickup 99% of the time and so there is no reason to get a pj set since am not going to use that bridge pickup anyway, i found the geezer butler signature pickups just the p one new for 90-100eu and at the same price they were some other like the spb3(which my fender pbass came with) from seymour duncan and i also think i saw some dimarzio ones in the same price point.
My question now is what do you think will suit me the best keeping in mind that the bass is in low tuning and with high gauge strings.
I've uploaded an old photo of my bass below.

What is wrong with the pickups you have now? What kind of music? Choosing pickups is basically a combination of power (feel) and EQ (construction). But you have to know where you are to see where you want to go. Just hoping for 'better' usually results in a sideways step.

I thought you could guess by the tuning but anyway, I play melodic death and nu metal the ones I currently have are just very bad sounding this is a budget bass were talking so the pickups in it are very cheap aswell

What don't you like about the current pickups (sound-wise, not price)? What do you want out of a pickup change?

Recently I played a 5 string bass that was 'made' for metal and without any eq or effects it was sounding 'growly' , dark and very punchy.
I don't know how else to describe it.
