I think it's all about the specific execution. I think my problem with most active basses is that they start with a very neutral pickup sound and then the EQ is supposed to shape your tone. I hate that. I like my bass to start with a lot of character (like a P-Bass), such that the EQ, if one exists, can hover around 12 o'clock and just add and subtract a little as needed. I also like to have passive bypass for tonal options and extra gig-worthiness. A good neutral EQ shouldn't do much when it's at 12 o'clock.
