Head drops from t4, hands are t2. Anyway, as far as what is better then what I'd say.
Head: Allagan > AF2 Allagan is T4
Body: AF2 > Allagan Allagan is T1
Hands : AF2 > Allagan Allagan is T2
Legs: AF2 > Allagan Allagan is T1
Feet: Allagan > AF2 Allagan is T5
So plan according to what you and your shell are able to farm easily and get drops on. Because as stated the stats are not a big enough difference to waste mythos on something you can easily have allagan for. Bracelets and Feet are both T5 so those are pretty good to spend mythos on as it will be a lil while longer before most are farming that. As for feet, I have the points to buy them but I think Darksteel melded is also a good alternative. Same with bracelet, grypo is a good alternative if you don't want to waste points on jewlery.
Truth is I don't want to spend so much on DRG in the way of mythos. If you are running coil on a weekly basis with drg as your main and expecting to lot on gear then you will gear up soon enough. Its not like you need the af2 gear to farm coil, 1-4 can be farmed easily enough in darklight. Can save your mythos for another class.
