Knowing Extreme it's obvious to me why VH thought he would be a good fit since he had the technical vocal chops of Hagar, and could deliver quirky and fun lyrics like Roth could. But his voice was no longer up to it by 1998. You can actually hear him transitioning into his far-more shouty VH3 vocal style on the last Extreme album (in 1995). But at least that album still had some killer riffs on it, Eddie could barely even offer that on VH3.

But before that Cherone was actually fairly versatile, he even had a nice "normal" singing voice when he wanted to take a break from the heavier approach. Also the band loved to do harmonies so their vocals never got too samey.

Not gonna lie, the 2nd and 3rd Extreme albums are among my all-time favourites, their 1st is kitschy fun too (though far more generic). Nuno Bettencourt was the kind of guitarist who had to pack every possible space available with a new awesome riff or head-spinning lick which I love (he was far more the star of the band than Cherone ever was). They were also too smart for their own good which always appeals to me, their big hit album was a satire of hair metal but people didn't get it so only their non-satirical ballads got popular. And then their next album had a 20 minute prog epic on it, so no surprise they didn't last very long.
