I am probably back in the 'give a shit' about my lawn game because of Allyn Hane (lawn care nut). Watched his vids many years ago when he was still in Indiana? Somewhere up north.
Ginga has some great tips, especially when it comes to diagnosing areas that are not growing right or have issues. Solid advice on how to approach those. He's also the one that got me to doing dethatching with the
Sunjoe Dethacher. Haven't rented a unit since.
I'll check out G&G TV, haven't seen that one.
Pete at GCI is a good dude and I kind of went with black beauty ultra as a test after watching his series of tests on his own TTTF vs KBG and Rye. If TTTF is resilient in his hot summer climate, I have high hopes it does well here.
I would add
Silver Cymbal:

Down to earth and simple explanations for those without a lawn degree. If you just want short easy vids to get a start on a lawn reno when you don't have prior skills, he's got a series of solid vids.

Lots of info on leveling, striping, watering without in ground sprinklers, quite a bit on lawn types as he has gone through several different species over the years.
We could get into connor ward and others, but if someone really wants a jump in point and doesn't want to surf shit loads of videos Lawn Care Nut and Silver Cymbal are a good place to start. SC has really short videos and LCN has a community with forums and newsletters where you can get info with details specific to your grass type and area of the country in written form. His vids tend to be long, but worth the view if you want a deeper dive.
