I used to watch CaptainSauce a lot, and I did like his Life of Kevin videos. The only thing that bothered me about his videos was that he obviously used a lot of mods, but never explained how he used them, leaving most people to think that this was all a part of the Sims 4. It almost came off as disingenuous to me. At least CallmeKevin tells you what mods he'd using.
I ended up unsubscribing from him because he started doing only VR all the time, which wasn't my cup of tea.
MattShea also used to do some good sims videos back in the day, but all he really plays is BattleCats now.
At least we have CallMeKevin and GreyStillPlays who still play the Sims. And of course, we have the regular Sims youtubers, like James Turner, Deligracy, Carmen King, Plumbella, etc.
