Jugs are holds that are AMAZING because they have such a good grip it is like holding anything with a hard handle almost like your fridge door but turned the other way, they are the best hand holds ever... but with feet it's not the best but they are still good for your feet but sometimes it's hard to control your feet on them. Crimps are sometimes the worst hand holds they are very, very, very small, you have to squeeze your hands so hard just to get a little bit of a grip they are the worst for hand holds. Now if you are using crimps for foot holds they are better than jugs because you can stick your foot into the wall and use the crimp as good balance crimps are better for feet holds. Granite, granites can be any hold but it is made out of real rock so I can't really define granite. Slopers are used for hand holds but are terrible! They are what they are called slopers because they slope down and your hands sometimes slip if you don't have chalk. AND MORE is the worst hold EVER! Just kidding they are not holds but there are many types of holds other than just those.
