It's easy to use and has many different templates which can be used, it's not too expensive for what you get so i wouldn't have any complaints about this one. I do like how it was easy to customize as well. So far nothing in particular that i dislike. There are some other plugins out there that offer more flexibility than WPBakery but they are generally a little bit more expensive. If you need a lot of customization then WPBakery is probably the best option. We were looking for something that would help us build our website without having to know code or understand HTML. This did just that.
