TONIO!!!!!! ^_^ well to be honest..adsense doesnt really give any perks to medium sized channels like mine...I think those who really get good perks are ones who are really big with over 100k subs and above. With that said, I look at signing over to a network like signing my soul away for some odd reason. Hence in my last few posts about fullscreen partnership was probably fenced over to a less positive note. With adsense, your account is yours, you only share revenue with YouTube, but with a network it goes 3 ways, hence if you are talking about earnings, I can't say for sure, but I think you earn more being and indie channel. I recently got an offer from Stylehaul and I've been emailing both stylehaul and fullscreen to get the best bet and Stylehaul shares 50/50 with fixed cpm which is higher then your current cpm but it is shared 3 ways nevertheless.
So if you are going to sign with a network, I think it is always more advisable in terms of earnings that you calculate your current earnings compared with what you would get with a network and do the math from there. As for me, earnings do matter in a sense other than protection and so forth, because I think content creators put in alot of effort in their videos and should be paid no less than to what they are entitled. It really differs from each individual. I think if you are a small channel looking for better opportunities to gain more exposure, then its great to join a network. But as for me, even without a network, I've been gaining a steady growth, that's why i made it really clear to the network managers I was negotiating with that with or without them, I am still doing okay.
I think it really boils down to individual preference.
