>Spring used to be big but today JavaEE is probably better
Could you elaborate on that? I am seeing Spring (Boot) used everywhere, only JavaEE projects I came across were legacy N>8 years old.
Spring is probably the biggest.
My point was that I personally find JavaEE better.
Edit: Personally I'd also look into Quarkus etc if I were to set something up today, but I don't belive it to be relevant to the original question.
