If you don't mind me asking, how old are you? I thought you were ~28. That would put you at 11-12 in 2000. Before 2000, I knew Bubba, had smoked Bubba, and so had the rest of CA. It's a strain that (according to the "Story") originated in CA. Regardless of where it came from, everyone, and I mean "Everyone" knows the Bubba coffee musk. I have never heard of, smelled, or smoked something with a fruity nose/flavor trying to be passed as Bubba. If it doesn't have that Bubba coffee musk, it ain't Bubba. I grew Bubba years back, when it was strong in the scene and took over OG for a bit, then lost it when everyone and their grandma started growing it, demand flopped back to OG's.
Even in a Google search, I can't find anything that says Bubba smells fruity.
Here is M5. This is the Bubba dominant (one of, 8 and 9 are also Bubba dominant) of the Bubba crosses (also includes 7 and 10, which are GSC dom). I easily identified these as Animal Cookies x Bubba due to the unmistakable Bubba coffee musk. Animal is the known mother from the 1/8 acquired at one of the top clubs in LA that grows their own, so well established that they do not accept new members/walk ins without having a current member offer you a "Friend Reference". They also have legit Bubba, coffee musk.
Looking at your pics, bud structure is kinda similar to Bubba, which is odd. Maybe someone popped some Bubba bagseed and ran with the name due to it's popularity.
I'm not out to contradict you, or knock a cut, but real Bubba has a strong coffee musk, 1,000% sure, I'd bet my dick on it, and this goes back to before you were smoking, before you hit puberty. (I'll be 40 in a couple years) No disrespect intended with the "puberty" remark, just utilized for "effect".
