I don't know about that. It comes down to the value of your resources versus cores/tickets. Heavy 1 to Heavy 2 is a 15% increase for 4* guns, and if I'm sitting pretty at 200 tickets and some amount of cores but not exactly capping resources, I'd much prefer to go for one craft at a higher percentage, since I know I can't afford multiple crafts at a lower tier anyway. Basically, higher tiers saves you resources, lower tiers saves you tickets/cores.
