Fire vs Renpy?

Fire has many faults. As a frequent user of Fire I come across a bug a day at best. Clearly there are many more improvements Fire can make with alot of trial and error yet in many ways it's come a long way to become what it is today. Compared to the earliest designs, I find Fire much easier to use now than before since it became very user friendly. It's a given fact that Renpy can hardly compete with the current Fire Engine which surpasses Renpy in many ways and continues to develop unlike the predecessor. Fire shows infinite potentials for further improvement than Renpy at this stage of developments.
