With Griezmann you just can see his class. The man oozes it with his every touch. Can't see that with Coutinho. All I see is fancy footwork in the Brazilian.
Honestly Coutinho looked brilliant the first few months as well - especially technically. Griezmann is the same, technically flawless - but we will see how he adapts to the team in a compromised/not ideal position (rw?). I have a better feeling with him though, because hes much less of an individualist than Coutinho.
