Both are very good, durable handle materials. G-10 will be a little lighter, more resistant to temperature change, and if appropriately textured, grippier. Aluminum will be a bit more rigid and resistant to impact (e.g., if you drop the knife), although it'll also show scratches and stuff.
Both are more than durable enough for even the most extreme conditions a knife will encounter, so really the main factor should just be which one you prefer the feel and look of.
