Well if it was just subscribers vs views then it depends what kind of subscribers. I'd rather have 1 million views than 1 million subs who just came from sub4sub or something similar.. but I'd much rather have 1 million actual fans who really enjoyed my content and kept coming back for more than 1 million views. (Besides if I had 1 million+ active subscribers I'd probably be getting like a million views every week anyway)
Already got close to that in views too so subscribers would definitely be my pick.
