I couldn't have said it better. I use Coblocks. Now every other block plugin I try to install has more or less the same set of blocks. Accordion, Tabs, CTA, Heading, Layout/Row/Section and Buttons are the most common blocks. Of all the blocks that I have used, only Ultimate Blocks, Coblocks and Font Awesome Icons into Editor appear to be something of use.

I am still waiting for a good Table block plugin.
