Focusing only on the refund: the refund feels good, but the real question is whether the tax rate on withdrawal later will still leave the RRSP ahead of the TFSA.
Spending the refund automatically: the RRSP usually becomes much stronger when the refund is intentionally reinvested or redirected to another useful account.
Ignoring carryforward and actual room: this page uses your room estimate, but only CRA can confirm the real deduction room for this year.
Skipping the account comparison: if FHSA or TFSA are also legitimate options, the RRSP should compete on actual tax value, not on habit.
