I normally prefer passive, so that got my vote. I dislike most active-only basses, including the first two I owned, an Ibanez SRX500 and Fender American Deluxe P (1999). I'm not crazy about most EBMM basses either, though I've liked a couple. So for years, I didn't expect to end up with an active bass.
Then I bought my G&L USA M-2500, and it's just fantastic. I've been surprised how much I've liked it, and I've played it for several gigs that didn't require a five.
So really, it depends on the bass, but despite the M I still have a strong bias toward passive.
