In a long term sense, as in the number of years I have watched a streamer, I would say Stop & Step. I have watched him since 2015, and I like that he plays a mixture of fruit machines and online and plays a mixture of old and new. Pretty laid back personality. His schedule is not overly manic either. Roughly 2 hours of content per week, split over 4 days.
The Bandit was my favourite while he lasted. Great banter in his videos and had a good feel on what games to play e.g. the BTG ones. Content wise, he used make 3 videos per week in 2017. Always on a Sunday, plus 2 week days. Then it became sporadic after 2018. I hope he returns.
Both the Bandit and Stop & Step have done stake challenges.
I followed Chipmonkz from late 2018 until the first lockdown. I liked chip and Jord as personalities and they had good stories to tell about their pasts, about work, living in Oz etc. In 2018/19, their schedule was a video each week day at around 30 minutes each. When the lockdowns happened however, they increased their output to 3 or 4 videos per day. I was still working, so I found that schedule difficult to keep up with and so I think they were targeting people who were furloughed. Stop & Step on the other hand remained consistent, albeit everything having to be played online (no arcades).
I have followed Ryan Slots (formerly Pig’s) as well but he keeps disappearing / reappearing. Sometimes his channel shows up blank, then his videos reappear again.
I also like Casino Grounds. They make 15-minute compilation videos a few times a week of different streamers, and I like the editing that CG does with the various internet in-jokes they use.
