Use SVG or bitmap images?

I am currently creating a GUI for my first game in Unity and I would like to know if I should use SVG files instead of bitmap images. The reason I wonder is that Unity seems to have some kind of SVG importer (it can be installed through the Package Manager, it is still in preview mode). Also in the asset store there is an add-on available that does the same (Simply SVG). If I could use SVG, I do not have the problem when I use several resolutions.
