Through it all, I'd say my fav. voice actor for Logan would be Steven Blum (multple uses) with Mark Hamil (X2: Wolverine's revenge) a strong second.

Steven Blum. 

steve blums good, everyone likes steve blums wolverine, he does his voice in everything now, i also liked mark hammils voice in wolverines revenge, but ill say my favorite is scott mcniel, because im a big fan of x-men evolution.

Steve Blum.

 Steve Blum.    

Cal Dodd because even though he captured wolverine's feral side, there's a bit of humanity laced with it, or maybe I'm just feeling nostalgic right now. I also like Wolverin'e grumpy moments from the original animated series.

Scott Mcneil for me

I like them all on some level, Marvel does a good job of casting voices for Wolverine. Steven Blum is very good, I liked him the moment I heard him, I said THAT is Wolverine, but you can tell eventually he's actually trying very hard to keep that kinda voice. In the Wolverine and the X-Men when he roars it comes off as more squeaky sometimes, not very intimidating, for the reason it doesn't appear natural I say Cal Dodd is the best voice actor I've ever heard for Logan. Hell you look at the old school X-Men Animated Series those voice actors are some serious stuff, that show could quite possibly have the best voice cast I've ever heard, you ever really listen to Apocalypse? That guys no joke

Steve Mcniel is my fav.

 
Every voice actor is just a pseudonym of Scott McNeil.

I've liked all of them, but I probably have to give #1 to Cathal Dodd since his is the voice I always hear in my head when reading the comic.

Steven Blum has pretty much become the definitive voice actor for Wolverine, much as Kevin Conroy became for Batman

Steve Blum

When ever I read the comics, its always a combination between Cal Dodd, Mark Hamill and Scott McNeil all rolled into one.

I happen to be a fan of Steven Blum, so I still vote Blum.
