Not a tough call at all. You can either be at the front of the hiring wave or the back. That’s the difference five years will make. You will never have a better opportunity than you do right now if airline flying is the ultimate goal. Sure, get a Guard or Reserve slot if feasible, but get your seniority started NOW, not five years from now. Otherwise you will be 3-4 THOUSAND slots lower in seniority your entire airline career. Ask any sixty-four year old Captain how much that would have cost hem.
