Mid 90's to early 00's SNK deserves all its accolades but there are a lot of other great stuff out there. Pretty much anything on the Capcom CPS2/3 looks incredible. 90's Irem is excellent before there talent was poached by SNK, In the Hunt, Undercover Cops, Gunforce 2, R-Type Leo and Ninja Baseball Batman are games you should check out. Late Konami stuff like Mystic Warrior and Violent Storm are top notch. For really underrated high quality pixel art check out the IGS PGM which is a bit of a successor system to the Neo Geo, there version of a Metal Slug like game >>12014397 is posted up here. There was also the SV-T an arcade system based on Saturn hardware, a lot of the best looking pixel Saturn games are ported from it, Cotton 2 and Hyperduel stand out.

Pretty Soldier Sailor Moon by Gazelle is one I'd like to spotlight.

The arcade game is a step above those two in everything, graphics, music, number of on screen enemies, though it is much more difficult, you got to set the difficulty to lowest if you want a console like experience. Definitely worth a play.
