Mentioned this loads back, but the most important stat to look at when judging playmakers is Shot Creating Actions per 90.
This is an all encompassing playmaking stat for the BIG DIRECT playmakers (Kevin) and the more subtle ones (David Silva).
Basically it's simple, is what your doing causing the team to shoot the ball, that's playmaking in a general sense.
Here's our team in all comps:
Ignore Perrone as an outlier currently with barely any minutes, and you can see the clear distinction for who makes our team get chances to shoot (Kevin, Riyad, Foden and Grealish).
And the only reason Foden just edged Grealish here is due to his most recent game where he had 7 keypasses.
So in Grealish's own special way, he is "playmaking" more than enough for this squad and is in line with our elite bar Kevin who is an anomoly of a playmaker (as was David).
Now in terms of goals, no argument from me there, he can do better.
The main issue here is that how do you play Phil, Grealish and Mahrez? We seem utterly reliant on the wingers to create our chances, with Kevin the only one in the middle. Gundogan and Bernie are "okay" in this department, but could be a consequence of our playstyle as well.
