'Shinko tires' is pretty generic. Raven is a sport touring tire, Advance is probably a supersport tire (totally guessing here).
I haven't run Shinkos myself (other than the random round black one I had mounted in Arkansas when the wonderful roads down there killed a tire, it was a glorious death) but some have in my former world (Suzuki Bandit, oh the horror) and they run the daylights out of them, good wear, tolerable handling and better price than a Pirelli Angel GT or Michelin PRx.
