I'd not recommend using the older versions because it corrupted my library, and it removed some photos from Flickr after I removed a set (I hated it so much... it wasn't supposed to work like this, Apple), and made the original ones very hard to find. The new Photos app seems way better, though. However, I admit my trust in it is not great either because I'm afraid these experiences might happen again... So I'd either stick to Lightroom or go to something light that I know I can always just rely on organizing the files by directories on my filesystem.
