Hi,
I’ve built with Love, MOAI, and Corona (as well as some other minor players).
I’d stick with Corona. Corona is able to keep up on the current needs of developers, has fantastic documentation and support, as well as, making packaging and distribution very simple.
With both Love and MOAI you are also required to be more involved in the code base, where Corona has already handled the most common (and uncommon) use cases for mobile and desktop development.
Things you should be looking out for are:
- How much extra code do you need to add to use a certain piece of functionality?
- Can you release on all major platforms without additional toolchains?
- Are the engines kept up to date? Is the support good? Are the people nice?
- How quickly are support and bugs handled?
Corona excels at solving all of these problems. They have daily releases, as well as an amazing forum full of really knowledgeable people, who are very willing to share help and other feedback.
I hope that helps a bit. Perhaps some others will chime in as well.
Cheers.
(Full disclosure: I’m a Corona SDK Ambassador, but that doesn’t change my research. Opinions are still my own.)
