If you do mostly low or mid gain with some occasional high gain, maybe Abraxas would be a better alternative. I haven't compared it to holy diver in a same guitar, but in different guitars (both LP style) Abraxas had a bit more vintage and organic tone, and also a bit less output. Also maybe a bit better clean sound as well. Holy Diver had a more saturated and modern sound.
Both were smooth in the highs and considerably less ice picky than the bright stock pickups I replaced them with. No need to tame these down with the tone pot.
Abraxas does high gain just fine as well, even though holy diver was a bit more suited for high gain applications. Still, I had some really meaty Opeth-style high gain sounds with my Abraxas LP, so it's definitely very versatile. Diver had more push and compression for sustaining lead work.
For neck, you can go with VHII, but it's slightly on the bright side of things. If you want a fatter, fuller neck sound, go for Emerald neck, which is reaaaally bluesy and fat.
