I like that it's easy to use once you get used to how everything works together; there are many different plugins available in this software so if something isn't working as expected, just keep trying until you find one which does work with your needs! There really aren't any downsides at all when using wampserver - my only problem was finding enough time (and energy) to learn what each plugin did before installing them.
It took me quite some time but now I'm able to do almost anything without having problems or needing help from anyone else.
