Jomez has distanced themselves from the other producers and quite frankly they make the other ones look dated. The best way to support Jomez imop is to simply keep watching their videos. The more plays, the higher the perceived audience, the more they can charge for commercials, etc.
I don't really agree with this tbh (my comparison points being SpinTV and CCDG). I think they have things they do better than others, and things they aren't as good at. The main differences are stylistic over technical prowess.
The one thing they have going for them is the flight tracker, but now CCDG is doing radar gun stats, so...you could kinda argue that one either way. Both of those things are more of a drain on time than tech.
Also - while I'm not advocating it's more sustainable - I definitely will say that contributing directly (Patreon, buying merch) does much more for the recipient than indirect contirbution (YouTube views -> Ads -> Monetization minus YT's cut). I suspect you mean direct ads or sponsored content, which is helpful but not lucrative yet, because it adds complications to the post-production workflow - which risks time and more potential mistakes. The worst is screwing up an advertising slot, because you gotta do the right thing and make it up to them, which cuts into the bottom line.
