Is Axelsen severely underrated?

Over the years, I've occasionally seen top10 lists of the best badminton players of all time. I've noted that it's quite rare that Axelsen features even in the top7 or so. In many cases players like Peter Gade and Morten Frost are even placed higher than him. This despite the fact that Peter Gade and Morten Frost never won the world championship nor the olympics. Axelsen has won both twice.

Doing a quick Google search, I'm unable to find any websites that actually puts Axelsen in the top5 of all time despite the following accolades:

2x world championship gold
1x world championship bronze
2x olympics gold
1x olympics bronze
2x all england gold

I'm finding this quite odd. What's up with that?
