Boots

Depends if it's from scrolling or pot.
If you have any %dex, and it's from scrolling, I think it's definitely better.
Weapon Multiplier * ((4 * Primary Stat) + Secondary Stat) * (Attack / 100)
So, say you have 20 str and 1000 total dex. You also have a perfect 150 attack VIP bow (a gift from a friend). You don't have any WG's or weapon attack on any other equips.

Formula:
1.15*((4*1000)+20)*(150/100)
1.15*4020*1.5
6935
That's what we'll use as your base attack.
20 dex+1000 dex=1020 dex.
1.15*((4*1020)+20)*(150/100)
1.15*4100*1.5
7073
2 att+150 att=152att.
1.15*((4*1000)+20)*(152/100)
1.15*4020*1.52
7027

As you can see, even with no %dex, 20 dex is quite a bit better than 2 attack.
