Hi there, cake!
All the engines you mentioned have good reputation. Personally, I use AGS and must say it is very flexible and overall problem-free.
It's true that the games made with it are not portable to web browsers (just yet) nor to Macs. However, AGS has the great benefit of a large, friendly community, who will be interested in helping you with your game's development and commenting on the finished product later on.
