looking for a good gallery plug in

Hi I’m looking at creating image galleries probably using a lightbox. I want to show thumbnails.
Any advice from someone that uses a lot of galleries would be appreciated.

I was looking at couple of the plug-ins. Next-gen gallery and lightbox. I’m thinking about going with lightbox because it uses the existing wp gallery.
There are so many option I just want to get some input before I decide.
Thanks
