Around me, all the KFCs are substandard while most popeyes are actually maintained better. Although there is one popeyes somewhat near me that used to get in trouble for dumping oil on the side of the parking lot. I guess it all depends on your location.
I've been using Kbin and Lemmy so far and I like both, but Kbin seems much more stable right now. I like kbin interface a bit more and the ranking algo seems to work better (there an issue on lemmy with hot and posts being added that should not be there). Kbin also let's me sort by 3hr/6hr/12hr in addition to normal sorting options.
