I haven't really messed with the US mediums, I went for the Hellcat instead, which I think is a blast (at least once it gets the 90mm), especially compared to the Panther V. Though I also enjoy my IS and KV-3. The French could be fun, so could the Brits. I do have some slots to play around with now that I got that free crap premium and that chinese low tier. Sounds like going chinese won't be that much fun, though they do have ridiculously high tier lights. To bad that that seems to be mostly pointless since the high tier mediums eclipse them.
