If by "grade A+" you mean "literally far and away the greatest political strategist in the Star Wars franchise," yes.
lol
Palps couldn't very well directly command the day-to-day Separatist military operations for obvious reasons, even if he were capable.
Anyway, we have no evidence of Palpatine's skills as a military tactician. He deferred that station to others. That said, as a strategist, he shows extreme competence even in military respects as the author of Operation Shadow Hand in Dark Empire that was extraordinarily successful.
That's the difference between tactical and strategic spheres. It's also the difference between commanding and being commanded. Every military leader has subordinates "executing a lot of the nuts and bolts."
