Some logo variations done in half a day (choosed the 4 best ones between 10)

Best thing vs Illustrator is the snaps/array/trim/cont. arc and a lot more ! Also small details like in the last one, used flow for text + fillets on the "cog" edges.
Would have take 3x more time in Illustrator.

I didn't even exported them, just used the screengrab shortcut :)
