Drain STH is the only '90s metal band from Scandinavia I can think of that I liked. Are there some specific bands you are thinking of?
Nightwish
To answer the topic, yes, I defintiely think so. I listen to a tremendous amount of Scandanavian bands. The whole melodic death metal scene started in Gothenburg, Sweden. Then you have the melodic/power/gothic metal stuff from Finland, Norweigan black metal.
So those nordic countries plus Germany tend to provide many of my favorite bands:
Finland - Nightwish, Amorphis, Sentenced, Stratovarius, Poisonblack, The Dark Element
Sweden - In Flames, Dark Tranquillity, At The Gates, The Lurking Fear, Soilwork, The Haunted, Scar Symmetry, Soultion .45, Sabaton, Hammerfall, Arch Enemy, Candlemass, The Crown, Entomed, Bloodbath, Evergrey, Tad Morose, Inmoria, Morgana Lefay/Lefay, Nightingale
Norway - Dimmu Borgir, Emperor, Covenant/Kovenant, Immortal, Circus Maximus, Pagan's Mind
