I've tried several other popular Joomla galleries, but seriously none of them come even remotely close to Simgallery. The community features are so important to any website that focuses on making their users share photos.
Easy to install, without any hiccups. I would suggest though to make all the modules and plugins installable together with the component, like how some of the other extensions do it. Overall I strongly recommend this extension. 5 stars.
Thanks for the review and great suggestion! We will definitely add that feature in our future releases.
