Rough estimate: 100 att clean sky skis, +5 str 115 att clean reverse -> 145 att skis, 160 att reverse, let's say 161 and ignore the 5 str. You can also use your own numbers

Without SI: Skis operate at 990/930 premium so 6.45% aspd boost,
With SI: 870/810 -> 7.41%

1.0645 x (57 + 145) = 215 -> 215 - 57 = 158 att reverse to match. So reverse will be better in this scenario, but remember att pots will change everything.
1.0741 x (57 + 145) = 217 = 160 att reverse matching, so reverse is still better by a bit.

I did not factor in DEX, and in this case, it will favour with more attack, so for sure reverse is better. But as you can already tell, reverse is only better by so little, it's better to go with skis to future-proof yourself. And I don't even think you factored blessing or even att ring. (8 cape, 19 gloves, 8 shoes, 11 naricain, 3 lilin, 7 belt, 7 blessing from aran ring, that's already 63 att by my standard and that's pretty reasonable if you're thinking about perfecting a weapon) And this is without a warrior pot, so that's easily 75 att base without weapon.

1.0645 x (75 +145) -> 234 - 75 = 159 reverse
1.0741 x (75 + 145) = 236 - 75 = 161 reverse

So reverse still wins under normal circumstances. With better attack pots or apples, skis will be better. So it looks like personal perference to you, reverse will get like a couple more att from levelling too.
