Bro I’m still rockin’ jQuery. I did some projects using React, then stepped back for a bit and asked why, then never used it again.
IMO React is a response to a problem that not all websites have (complex state-dependent nested UIs). At a certain level of complexity it's worth it, at another level it's necessary, beyond that it's insufficient... but below that it can totally be unnecessary and more pain than it's worth :)
Go with what works for you and your team!
