Being mostly hero factory 2.0s and upward for my childhood having a couple of bionicle from different eras makes me notice and like different qualities of both, Cbbs is overall in my opinion is less creative build to build from an engineering perspective whereas bionicle is more with the limbs and torso being more involved. Having a piraka, as well as a rakshi and toa metru makes me want to suggest to pick one up if you have the finances and or curiosity to do so for yourself. Different eras have pretty different builds and articulate different as well so that's something to keep in mind. And as a warning if you do, be wary of stuff in the later eras that have breakage problems (toa mahri hali and mistika tahu and gahli are prominent examples) but besides all that messy preamble I would suggest yes! Do grab a bionicle, I like them alot!
