I've played several Valentis, they're very nice Fender style instruments. I like and own many Fender style instruments including a couple of my Brubakers which nail the Fender Jazz vibe.
Between the brands they're two very different types of builds. US Brubakers are built from scratch. You can choose any woods, any scale length, any neck width, finish, etc. Have a radius you prefer? No problem. As far as flexibility goes Kevin has built basses from three to twelve (non-octave) strings. Lots of versatility in tones too, anything from a P bass to instruments that hit so hard they scare some players.
Four main body styles, a double cut (NBS), a singlecut (KXB), a Jazz style (JXB) and the Phoenix, a fairly radical singlecut. And other custom one-offs. You can also get a bass with multiple interchangeable preamps, they swap in less than a minute. The combination of massive clean sound with super low action takes most folks by surprise. Of course you can raise the action and turn them down if you prefer.
My six string JXB-6 Custom was modeled after my 78 Fender Jazz... Same scale length, heavier Maple body and we lined up the pickups so that they're in the same position as my Fender when the dual coils are split... It sounds eerily like my Fender would with six strings. And when the coils are all on it goes big. My KXB-6 on the other hand doesn't sound like a Fender... and this particular one wasn't built with that in mind.
So there isn't one Brubakers sound or look or feel, they're all variations on a very high quality instrument. That's why I own and gig predominantly with them. I play pop, gospel, classic rock, jazz, progressive rock, funk, r&b, country, show tunes, whatever, mainly fingerstyle but I can and do slap when the gig calls for it. Mainly sixes and fives, fretted and fretlesses, active and passive. They all kill IME.
