Female Dwarf generates stat weights based on your character's current gear, but has trouble with haste values. Zeherah recommends fooling with the haste values above and below the initial input so that you can see if the weight generated is stable.
So -- Female Dwarf will give you your own unique weights, but you'll have to play with the haste values to ensure that that particular weight is accurate. Once you get those weights though, any changes to your gear will require recalculation of your weights.
If you want to be lazy about it, AMR is close enough that you'll do ok. FemDwarf will likely give you more precise numbers if you play with it a little.
You can also use SimulationCraft yourself and compare those weights against what AMR and FemDwarf provide, for a third point of reference.
