[Pokemon] What makes a Great Ball stronger than a Poke Ball, an Ultra Ball stronger than a great ball, and a Master Ball completely inescapable? Not to mention all the other kinds with different effects.

Well going off the assumption that pokeballs are basically cages or rooms that are locked from the outside, then each one has a different lock. With the master ball having the best lock money can buy, and Poke Ball having an average lock.  





For stronger Pokemon, you want to weaken them badly, and maybe paralyze them with spores to make it hard for them to escape before you lock them in in your normal lock that takes a bit to close. While master balls are locked the instant a Pokemon is forced in and are too hard to try and break out.
