It's an nle like after effects is one. It's not not an nle but it's roots are elsewhere so because of that, it's hard to see it as one, despite advances in the software.
I switched from Premiere and Vegas to Resolve to work on video editing. It's as much an NLE as any other software and behaves exactly as one. I don't use Fusion at all, I solely work in Edit mode and it does everything I need as well as Premiere did. It's even more stable and comes with more in-built effects that I manipulate by automaations directly in the time line.
I don't know why you're saying it's not a "real" NLE.
Scary new technology that wasn't around back in the day. Grandpa Simpson said it best: "I used to be with ‘it’, but then they changed what ‘it’ was. Now what I’m with isn’t ‘it’ anymore and what’s ‘it’ seems weird and scary. It’ll happen to you!"
