Random, regular adopts are my favs but I also like appeals in general, since it actually forces you to come up with ideas and actually write them down. If I see a cheap adopt or an adopt that just looks cool, I'm just going to buy, I won't often think, "What am I going to use it for?" I'm just going to buy because I like how it looks. So appeals break that habit and I feel like a lot of people should do it. Not always, but it does weed out the people who adopt just to adopt imo.
