0.25 fin oral vs 0.3% topical fin. Which ones better?

Hi, I am looking to pivot from oral fin 0.25 mg to topical just to try if 0.3% fin solution is actually more effective than the low dose oral I have been taking. Which is the better option here in terms of stopping hair loss? Also is taking 2.5 mg minox oral with 6% minox topical solution ok?
