Alky Bracelets to AF+1 hands = (-4 Str +13 Dex +800,000 gil) that's about 10 raw accuracy for weponskills.
In general you can split it down the middle and have the best of both worlds, use Str for WS and Attack for TP etc, in most cases. (This should be obvious) as per your question specifically, I think pretains to WS gear; idk, just feel it out, they're really big melee hits, and bound by almost the same laws.
I personally looked at the stats like this for WS:
1 Str = 5 attack,
So Forager's = an index of 6
Smiledon's = an index of 5
Or you can look at things usign "Eyeball Math".
Rules to Eyeball Math:
1)Circumstances must be calculated under 'best case scenario'.
2) under the 'best case scenario' isolate variables you are testing versus one another.
3) Compare %'s and index them based on importance based on aplication.
For instance:
Dusk Gloves versus O.Kote:
One adds 3% Haste and 5 attack, the other adds 20 Attack.
- 3% Haste is a 3% reduction in weapon delay.
- 'my' base set of gear excluding hands has 15% Haste.
- 'my' base set of gear has let's say 350 attack(for arguments sake)
The X and Y here are total haste, and total attack:
Dusk: 18% haste, 355 Attack
= 4% total increase in the amount of swings per given amount of time, and a 1.4% increase in attack.
~5.4% increase in damage?
O.Kote: 15% haste, 370 Attack
= 5.4% total increase in attack.
~5.4% increase in damage?
But here's the thing, which one will get you to Weaponskill faster?
If weaponskills are 50% of your damage, getting there 4% faster will net you more benefit. (I.E. haste trumps all in most if not all cases) for the 20 attack to trump haste you'd need to have a base attack of about 240.
For weaponskills:
Assuming you have 400 Attack and 100 Str base:
Forager's: 15 Attack, 3 Str
Smilodon: 5 str
Eyeballing it, you get either a 3.6% increase in attack and a 3% increase in Str. OR you get a 5% increase in Str.
If you were at 450 attack and 135 Str:
Eyeballing it, you get either a 3.2% increase in attack and a 2.1% increase in Str. OR you get a 3.6% increase in Str.
The other angle you could go is this:
One set I have 123 str, and the other set I have 125 str. It's a 1.6% difference in One stat ignoring the other. Now you can ask yourself a couple questions:
How much damage is 1.6%? If a normal weaponskill does 1,000, that's only 16 damage.
is +15 Attack going to affect me greater than 1.6%?
is 1.6% damage the 16 damage per 1,000 on only 50% of my total damage output worth 1 inventory slot?
In short, you need to find your Waterline. I am not going to waste my time and space for a 0.8% increase in total damage. I personally start to crack at around ~3%.
This long winded post is just my opinion. I personally am a little relaxed on gear mainly because I save stuff that has more utility, and will sacrifice a bit for simplicity.
