Next r4 recommendation

Masonator73

Hi all - I need help with my next r4. I am stuck between Kingpin, Absorbing Man, Tigra, and Hulk OG. I can awaken all of them and am pretty good using all of them as full 5 stars. I do have a 7* Titania so having the Abs Man synergy looks strong. Is there one overwhelming path here? Thanks!!
