Head to head tea brackets?

Today I stumbled upon a lovely YouTube project, pitting 32 mid-high end matches in a head to head, racket style comparison and competition. Found a few new teas and companies I’d never heard of!

I’m wondering if any of you know of any thorough, multi company comparisons like this. Doesn’t matter if it’s video, podcast, blog post, I think there’s a good value in people comparing different products all of a single type of tea.
