I think Chris is old school. I used to like him and Simon on Eurosport in the 2000 teens. Chris sometimes comes off as bored or jaded. Part of it is probably that commentating is not easy. Chris falls back on turns of phrase and occasional hype and platitudes. But I have been noticing that sometimes he also gives very good insights, and he generally has a good eye for under-rotation calls.
The sport is different now, and it requires good commentators who are able to consistently educate the audience without resorting to overdone superlatives. With Chris, it's a mixed bag. I actually think Johhny Weir is a good analyst, but not when paired with Tara (which is most of the time). Charlie & Tanith White were excellent and insightful together as commentators for every discipline, but they preferred to move on to coaching.
I really like Mark Hanretty and Ted Barton. They have fun together on the JGP. However, I could certainly do without their sugarcoating things and cheerleading for the ISU. I think Mark is usually quite good when he's solo. Still, that's not easy, which is probably why Ted & Mark will be taking over for Chris, reportedly, at some GPs this season. Jean-Luc Baker is also a very good commentator, but so far, he's only covered practices at U.S. Nationals. Many fans say that Belinda Noonan is good, but I have barely heard her coverage, since I don't have a subscription to the streaming channel she works for.
