Paint in a can is only diluted as much with thinners as when you mix it up to put it in a top feed gun that works off a compressor. The pressure required behind it only has to be enough to blow the spray particles onto the surface, so the aerosol is more then capable. Yes you can have a bigger fan width on a gun, and more coverage per pass, but with enough aerosol cans, you can get all the coverage you need. The main problem people have with rattle cans is the finish, it's either grainy from spraying too far away, or its uneven or has runs from inconsistant spray pattern. & finally, even when people do get those things right, the paintwork has orange peel, and if cellulose lacquer is used, it looks dull and comes off easily. If 2k lacquer is used, and the item was prepped properly, and it's mopped properly afterwards, I think you might be surprised!! If you had access to a proper oven to properly cure the piece, it would be better, but most people don't.
