In front of 16 bits console, i think that neo geo has better horizontal shmup.
For vertical shmup, pc engine coregrafx + cd has better vertical shmup.
Saturn and arcade have better shmup for sure.
But neo geo deserves his good reputation, games as last resort, viewpoint, pulstar, blazing star and twinkle star sprite have had a lot of recognitions.
So no, neo geo shmup are not underrated.
But aso 2 is an underrated shmup while it's an hidden gem. Certainly, the first great neo geo shmup just before last resort release.
