Better to save yourself the hassle and just update. The worst that can happen is you never experience the bugs, the best case is you notice a performance increase.
As a general principle, I don't install "beta" software.
Most of the issues that people have experienced seem to be with the web browser. I don't use the browser on the Kindle at all; I do my mobile web browsing on my iPhone.
