In my experience, most forums including forums which don't use a mobile friendly themes work better on mobile devices.
Forums usually don't have a large navigational sidebar on the left or right of the screen which can make reading them difficult on a lower resolution smaller display which is usually found on a smartphone and tablets. Forums also don't have a lot of stuff on the website like pictures, videos, and a third-party commenting service like disqus, and Livefyre which takes a long time to fully load like blogs.
But, blogs usually have one or two large navigational sidebar on the left or right of the screen, so they take up a lot of space if the template is not a mobile template. Plus, a lot of blog sidebars contain large pictures, text, and sometimes auto-play video which can slow down a website's loading time, and make slower devices run slower because auto-play video and large picture files can use up a lot of RAM, and CPU devices on slower mobile devices. A lot of blogs also use third-party commenting services from Disqus, Livefyre, etc which seem to make comments and the page load slower.
Some blogs with mobile themes also seem to run slow because the blog's mobile theme still have a lot of scripts, images, videos, and other stuff which slow down my mobile devices.
I notice my mobile devices like tablets, laptops, and some desktop computers seem to freeze or crash more often when I am on a large blog. But, my devices don't freeze or crash as often if I am a forum.
