I don't think so, both had the power of God, literally.
Michael does not equate to the power of the Presence, since the Presence can erase him with a thought.
So, that's good ol' fashion hyperbole.
On the other hand,
Synnar actually did battle the Presence PLUS all of Heaven and Hell combined, (includes Michael)
and while Synnar lost, it was a great battle before he did.
Anyway, we can't properly compare them
since Starlin's vision of the DC divine hierarchy is somewhat different than Carey's or Gaimen's.
One thing's for certain, although they were supposed to represent the same concept (Demiurge)
Synnar was written as a far more potent "demiurge" than Michael.
But again, different writers, different ideas portrayed.
