What are the best 4 stroke dirt bikes to get (from greatest to least)?

I'm thinking about trading my Honda cr85 big wheel for a 4 strike but I'm wondering what are some excellent 4 stroke dirt bikes that are about the same size as my cr85 big wheel?

Go look at the Yamaha TTR series, believe the TTR 125 or 150 should fit you okay.
Honda has the XR 125 or 150 also.
