You have to understand the diferences between popper and PBX. Tom has done a great job of keeping the software user friendly, a good looking front end that is easy to setup. He's also done a great job of controlling certain functionalities to avoid bloat.
Both have pros and cons.
PBX is for the folks that want a predefined front end that works.
It's not fair to compare the two as the intent was to give users options for front ends not to compete.
Bashing someones software that you are getting for free, and have not spent one second developing is not cool.
Maybe offer code, offer valid suggestions without the bashing.
I use both and both have features the other does not have. So it's a users choice. I also have both running all emulators no issues
Popper is for users that want ultimate flexibility and there is a learning curve, database and SQL knowledge is required if you want to take advantage of all of the features.
So if you want to spend more time playing and have a nice front end PBX is the way to go. If you want to spent more time enhancing the bling around the emulators popper is an option.
Be courteous to the devs without them we would have nothing...make a suggestion then make a choice based on your application. No one is forcing you to use either or.
