I have two of each. I like and play both kinds. I like and play all four of my basses. Life is good.
I'll expand on my short answer.
- I have a 4-string fretless that I intentionally wanted to be a simple instrument -- one MM pickup w/ series/parallel switch, volume and tone knobs. I had an active fretless for many years that I really loved, but found myself wanting to simplify the "tool" in the fretless realm and really focus ever more on what I did with my hands to get sounds that I wanted.
- I have a passive 4-string PJ. I wanted to have a passive 4-string in the stable -- just fits right in a lot of situations (particularly ol skool stuff) and is strung w/ flats. I wanted a fretted bass that forced me to be simpler in my approach to the instrument, and passive seemed right for that. And I really do vary whether I just use the P, or the J, and varying mixes of both, and that gives me a fair bit of variety along with passive tone adjustment.
- I have an active 5-string. I wanted a multifaceted instrument. It has an Aguilar OBP-3 preamp as well as a passive tone and the ability to switch to passive mode. It also allows me to switch the pickups between single coil and humcancelling. I have a lot I can do with this instrument on the fly, and that's what I wanted.
- I have another active 5-string. I wanted an inexpensive backup bass to leave in my office as I was having the occasional need to head out to play on short notice during lunch at a nearby rehearsal studio or after work. I didn't really care that much whether it was active or passive, but wanted a 5-string. eBay offered me an ATK for about $200 -- it was in the middle of the night, the auction was due to end within 20 minutes with only one prior bidder, and I said, "Ok, I'll throw in a bid." I won the auction. It's a terrific bass. I got lucky. It happens to be active. Works just fine for me. If it were passive, it would be fine, too. But it's not.
I prefer to adjust my tone options at the instrument when I play a gig. I prefer not to go back to my amp. Also, I am often playing through amps that are not my own -- at rehearsal studios or backlined gigs. I just want to find a basic sound I like from the "unknown" amp. I understand what the tone or EQ knobs on my basses do, so with amps I know less well, I'm a bit more successful tweaking my sound in these circumstances from my bass -- whether passive or active.
Peace.
