You had Netscape (Firefox didn't exist then) which was _super_ slow, or you had IE for Mac which didn't use Trident so had its own version of IE incompatibilities. Neither had a native UI, and Mac was a second class platform for both of them (as in IE for Mac was not a priority for MS, clearly Mac was important to IE for Mac. Although as I recall the IE for Mac engine is what formed the base of the mobile ie due to better memory usage, and mobile browsing was still not considered "real" internet in that period so the incompatibility with IE was presumably less important)
