Rangers fan. Rangers in the short/immedate term, maybe the devils in the medium/long term (5+ years).
That's with all things being equal today, without consideration to the Devils getting a very good pick in next year's deep draft or the Rangers potentially trading assets to make a run if they're doing well in February of any of the next few years.
History teaches us nothing:
We're 2 years removed from the Devils celebrating their tremendous offseason of landing Jack Hughes, PK Subban, Nikita Gusev, and Wayne Simmonds. That summer the Rangers only were able to add Trouba, Kakko and Artemi Panarin. I say this with righteous sarcasm because Devils fans were comparing Gusev to Panarin and saying:
Subban >>>>>> Trouba.
