I do have to say that I am liking the mic more as I use it more. Due to prior semi-successful experiences with mics over the years, I figured that reliance on a pickup would be necessary. So far, my adventures with the mic have been very successful, and frankly, I am likely to replace the Bass Master Pro on my Juzek with the Mic/Bass Max combination when I change my bridge this month, though I may have to leave it on for the periodic visitors/demos I do at the house, and so just add the Golden Trinity Upgrade.
Your volume situation may push you towards the Bass Max on particularly loud gigs, but it's hard to say since I don't know "how loud" loud is. But the mic does a great job for me in every situation so far, though I haven't been in a "real loud" place yet with it.
OTOH, you may want to read what other players' unsolicited comments have been:
