I personally like SocialBlade but that is also because I am partnered with them, I don't see any cons so far in my partnership with them and its a pretty nice one year contract so you are not really bound to long unlike other networks. The split is 60/40 and I am pretty sure your earnings do increase compared to just Youtube Ads since mine did have a bit of a jump in profit after I accepted.
The benefits of a network partnership would be a profile banner, watch page icon, and a couple of other stuff.
The specifics of SocialBlade would be they promote you *I personally don't think their promotion helps*
They do give you more support than if you were with just RPM since you can go to them for support.
They do have spotlight videos which can boost you a bit if you are chosen for one.
And just small things like that.
If you like all the little extra perks then I would go ahead and try to get partnered with a decent network, if you are doing fine right now then just keep doing what you are doing.
