Gearing question

Which is lower gearing? A front chain ring of 30 and rear of 32, or front chain ring of 24 and rear of 25?

30/32 = 0.9375

24/25 = 0.96

30/32 is 2.4% lower (easier).

It's 25.3 gear inches vs. 25.9 gear inches. You're not likely to feel that 0.6 gear inches difference. I'd say it doesn't matter.
