Convoy H2 vs Wurkkos

I checked the size for wurkkos hd15 and convoy h2 the spec says nearly similar dimension.

Some comments said that the H1 or H2 is a bit big compared to other 18650 headlamp. And they are too tight for skilhunt headband. Is the hd15 too tight too?

And considering other things, what are the pros and cons of each?
