I've had a BN5 for 23 years, and have played several MTD 535s (fretted and fretless) as well as pre-Gibson Tobiases. I've gotten my hands on a couple of Foderas at various GTGs over the years.
They're all different flavors of great. Though my BN5 has a wonderful preamp, it sounds so good in passive single-coil mode that I use it that way maybe 80% of the time. Mine is from the nitro-finish era and apparently newer F-Basses feel a little less rustic. Also the F-Bass ergonomics work for me, even though mine is over 10# it balances very well, and I honestly thought it was around 9# for the first 15 years I had it, it's so comfortable! I've played a number of BN4s and BN6s, and kind of regret not getting a Studio 5 instead of the BN5 - but all had similar tone, even the painted (basswood?) Studio I tried.
MTDs have a wirey woodiness - where there's both depth and clarity that's vintage-leaning but decidedly modern, top-notch construction.
TBH there are more than a few pro Fodera players who - to me - have some of the wimpiest, detail-free bass tones ever, and to be sure the demos that Bendy guy has done over the years are kind of the opposite of "the tone is worth the $$" to my ears. And they have so many options, I would definitely have to try one before ever putting down the money for a Fodera. But their design and construction are absolutely stunning.
