Remember, that other DM's AP was written on top of a setting developed by several people, so not only does the DM have much less work to do than you, even the AP's author had less work to do than you.
You shouldn't be disappointed by the realisation that the players enjoy the AP game as much as your own. Players don't factor the number of a campaign's designers into their evaluation of how much they enjoy it. In fact, given the demands of creating a campaign from scratch, you should give yourself a serious pat on the back for the fact that the players seem to enjoy both games equally.
After this campaign, take a break from world building for a while. Take a year or three. The work you've put into your previous campaigns will still be there if you decide to return to it at some point in the future. Meanwhile, take it easier on yourself and find something someone else has had to work hard at, so that you can just concentrate on running it.
