TBh I rate Hulkenberg very highly in terms of talent. It is a shame he has not been given a crack at a top team because he would surely be a race winner and challenging for a WDC as well.
Given a good car he is rapidly fast.
This is more of a failure of F1 in general than Hulkenberg that we only have 3 teams able to challenge for race wins. If they just keep the regs the same for a few years, sooner than later, the midfield will catch up to the top end and we would have a situation like 2008 where the entire field (or most of it) all were within about a second of each other. Also, we really do need another 2 teams on the grid. I'd offer Dams and Arden a nice deal to step up to F1. or any 2 F2 teams that are ready to step up.

I hope he exercises a bit of patience and waits to see what 2021 looks like. Just like kimi, he could come back and jump into a top team. To me there is no point going to Haas. He has done that kind of move his entire F1 career. Mercedes, Ferrari and RBR might have a seat for him in 2021.
