I use pokemon DB because it has all the information you need and you can find it all in less than 5 seconds. I use it over bulbapedia and serebii for this reason. However, one thing this site doesn't have is the moves of gym leaders. this is helpful information that I wish was on this site since it's my favorite pokemon info site.
Also if you could add the totem boss battles and the kahuna battles on the gen 7 game pages that would be great. Also, add a rivals page that shows the teams for all the rivals. :)
