Snickers is made by Mars, and their chocolate has always been higher tier than Nestlé and Hershey's. Mars also makes the (god tier) 3 Musketeers, the Milky Way/Mars (not sure which one is branded Mars in other countries), and their plain chocolate bar is Dove.

I think there's a Mandela Effect around Dove. I, for one, thought Hershey made Dove at some point. I don't know why. Hershey's does have a higher-end chocolate called Symphony, but I haven't seen it in years. It's creamier than their regular bar.

Look up Wilton's chocolate buttercream recipe. It's cake frosting. But nothing says you can't eat it on its own. Pipe it into Hershey's Kiss shaped dollops on a sheet of parchment/wax paper and chill, eat them like little mousse bites. It's basically a stick of butter, I think 3 cups of sifted powdered/Confectioners sugar, and milk to control the texture/consistency. Some people add vanilla extract — of course, you could hit it with whatever other extract to tweak the flavour a bit. Maybe you want minty chocolate? Peppermint extract. There are options.
