HelloGreedo isn't even a good channel. Granted I haven't really watched his stuff in ages, but I don't remember any of his videos having any merit, and as you said, he was very elitist.
He is, in some ways, a representative for all the "Only the OT is TRUE Star Wars!" people, moreso than RLM.
As for other channels, I think the answer is no. Every Star Wars Channel I have come across is either really low quality stuff, ill-informed, cringey, or in the case of StarWarsHQ, all three of the above.
If I was to suggest the "least shit" then looking through my subscriptions, I see;
>Dash Star
His videos are well presented and decent quality, and he has good presentation. However the content is usually meaningless and borderline clickbait. Recent videos I use as examples are one he did on Mace Windu possibly being still alive, and a comparison video on Grand Inky/The Son. Nothing interesting you wouldn't know already, or need braincells to realize it's just a coincidence, right?
However he did literally cry during the Thrawn reveal in his reaction video, and I love seeing that kind of passion in Star Wars;

>StarWarsCentral
This guy is sadly one of the "SUPER AWESOME STAR WARS CHANNELS" that barely talks about anything other than the games, because they wont admit that they never really liked Star Wars beyond the games. He doesn't upload regularly either, which brings him way down.
However, his pros are that he doesn't have a stupid goddamn accent like other Star Wars Vidya Youtubers, and he is probably the only popular one that I know of that hasn't been afraid to call out Dice on some of their bullshit.
>Official Star Wars Channel
No brainer
>BattlefrontUpdates
Goofy Voice, and a little kiss-ass-y, but the most regular uploader if you're into Battlefront/Vidya and like staying up to date with the updates and shit. Last resort for information.
That's it from me.
