SNES had better hardware (more powerful) than its chief rival the Genesis. Neither fully achieved overwhelming dominance and essentially split the market.
The PS1 had better hardware than its chief rival, the Saturn, which also had the distinction of being overpriced due to an overly complex architecture (dual CPUs).
Nintendo's main mistakes with the N64 was the insistence of keeping a cartridge based format to maintain full control over game production and prevent illegal copy distribution. Premium price or limited storage space, along with Nintendo's draconian publishing policies are what made 3rd party developers head to greener pastures with Sony.
Better hardware than the PS1, but limited storage space placed a compromise on games, regardless of processing ability.
PS2, being second to the 6th Gen after the Dreamcast, unquestionably had the most dated hardware by the time the generation was in full swing (by this point, the Dreamcast had already exited the market).
Nintendo again found itself with a reduced storage proprietary media format to reduce piracy and a continued loss of many third party projects despite its very capable hardware.
Xbox arguably had the best hardware, but being new to the console market (and late) never really stood a chance against the 3rd party publishing dominance Sony had already established.
