Yeah, it was nice. But the key thing you have to remember is that (popularity aside) the "wintel" platform was the laughingstock of the industry, literally anything >8-bit was a thousand times better. Until the Pentium and Windows 95 hit, they were almost totally unuseable.
The Mac itself was inferior in some ways (software-only A/V, much smaller game library) to other platforms (Amiga, ST/Falcon, X68k, etc…), but the OS (and hardware) was a pleasure to use (vastly superior IMHO to nearly everything else back then, and absolutely anything today, including OSuX), and what ports and original games there were generally outclassed every other platform.
In particular, for whatever reason, full-resolution square-pixel graphics (>320x240) with full palettes (16-bit palettes @8-bit) and full PCM sound were way more prevalent on Macs. Also, CDs caught on way faster with Macs.
In the first era you mention, there was actually a moderate but active Mac game development industry, but after the Pentium/Windows 95, all the other non-Mac platforms died. This coincided with a variety of stupid decisions on Apple's part (PPC, PCI, delaying Copland) and general industry trends (GPUs) that robbed them of their technical superiority.
From there until the x86 transition, Mac gaming was 99% ports, generally equal but no better than wintel gaming (with the notable exception of audio, even Linux ports had better EAX/A3D emulation) but delayed by a year or five.
I won't even dignify the post-Intel/iOS era with a description, since Hackintoshes are a billion times better than any trash Apple makes, and basically all the "ports" that exist are WINE wrapped Windoze games.
