All three of those, from what I know or hear of them are great choices to highlight. I don't currently follow TM or SG, but that could change. Asher gets as about as technical on things as I typically want to get, but there are times where I will foray farther into the inner workings of things in hopes of gaining a better understanding.

It's good to have folks like these on Steemit, that we can learn from, associate with, and hopefully grow to become like. Or at least grow to be our own versions of them. :)
