Let's make a fair comparison:
There were very little amiga games that were harddisk installable, while all pc games were.
Harddisk installable amiga games ran fine from the GUI, even the more hardware-heavy games, like Lionheart and Fightin' Spirit, while the vast majority of pc games weren't until 1997.
The avarage sound card until 1995 was the Sound Blaster Pro, of which synthesizer could not match the Amiga synthesizer by a long run. I remember buying the Sound Blaster Pro for more than 200 guilders, which was a lot back then, but I desperately wanted to get rid of the beeper sounds (and many old games didn't support it to my disappointment).
Many pc games before 1992 were released in CGA or EGA while their Amiga counterparts were all VGA-ish, at worst EGA-ish. Sound blasters weren't that common back then so many games were CGA + pc beeper and I can tell you that the audiovisual experience was heaven for the die-hard masochist. The colour magenta is still burned in my retina and the shrieks of the beeper still haunts me in nightmares.
Sure, the Amiga had it's share of Guru Meditations, but it didn't cripple the machine as much as the BSODs of Windows 9x, and while the majority of BSODs were caused by Windows 95, the Guru Meditations were almost all caused by badly written software (and therefore could easier be dealt with).
