I think it's 100% individual. I didn't feel like I learned enough, so I stayed in grad school. If you feel otherwise, you absolutely should follow you own path. I've interviewed and worked with hundreds, ranging from bootcamp to PhD, ivy league to city college, and i've seen so many - both - failures and successes, that reducing signals even to education in general, let alone some specific combo of it, without hearing out the person first, is a straight up bias.
