Like you, OP. I don't have a favorite. Before the ResurrXion relaunch, I was loving Bunn's Uncanny X-Men. I love Inverted Sabretooth, and I was digging his relationship with Monet, plus the direction Bunn was going.
Now Creed's in Weapon X, and Pak has been the worst writer for him. Creed has been nothing but a joke throughout this book. He's utterly moronic, completely incompetent, gets his butt kicked more than anyone, everyone on the team talks down to him, and he's automatically evil again with no build-up. To go from Bunn's great writing & plans to the downgrade that is pak is frustrating. All of Creed's character development was cut short & ignored when Bunn lost him to Pak.
So needless to say, my LEAST favorite is Weapon X due to the ruining of Sabretooth. I hope this book doesn't last past mid-2018, and Creed can be handed off to a better writer who will ignore everything pak writes.
Otherwise, I am following Generation X. But only to see Monet, since her story also got disrupted when Bunn lost her. And I am hoping the answer will be there for why she's not still with Sabretooth. Bunn took the liberty of showing they ran off together in UXM -only for ResurrXion titles to have glossed over it. I am hoping a reason is given, and it's not just Marvel having OMD'd it from canon.
