I've read quite a few negative reviews on Ubuntu and derivatives when a new LTS version comes out. As soon as a new LTS version is released the websites do a review. Dedoimedo & several other sites do this, it is quite rare for them to do a follow-up review on say Ubuntu 16.04.3.
As these point releases are done a lot of little annoying bugs are found and fixed. Well that is how it seems to me anyway. I found this with Ubuntu 12, 14, and now with 16.04.3.
