I have a few SU markers, lots of tombows, few prismas, quite a few Bics, few copics (sketch and Ciao) a bunch of alcohol markers I bought in Paris that are very similar to Copic orginal ( small tips), also quite a few of Marvy and Dee Grueing, and prisma pencils and OMS. I love all of them for different things. I use many different kinds.
Alcohol blend better in largers areas without streaks. Prisma Pencils or Knoor pencils I still love with the gamsol/OMS. Just depends what I am coloring and what look I want.
