Generally speaking, Sothink SWF Easy and Sothink SWF Quicker are both Flash makers, but the former one is for the green hands, while the latter one is for the professionals.
With Sothink SWF Easy, you can easily create albums, banners, cards, buttons with lots of templates and resources in it.
However, Sothink SWF Quicker is a great flash animation editor to edit an existing SWF file or create a professional Flash animation from scratch, and the users had better get the knowledge of actionscripts well.
Anyway, we suggest you try both products for a check; the experience is better than words.
Thanks for your support and have a nice day!
