If you're making logo's; Illustrator > Photoshop..
This.
At least, it is if you're trying to be a bit more than an amateur doing it for your own fun or whatever.
Good logos don't rely on photoshop filters etc, and creating them in Illustrator ensures you could wrap a building in the logo and it would be 100% quality, perfect resolution.
