In the grand scheme of things it honestly matters very little because if you have a decent raid group you'll be hitting turn 4/5 in coil with or without the +1 weapon. Honestly until they fix Twintania I'd say it comes down to whichever you prefer, do you like the darklight set or like looking like you just stepped out of ak? Are you fine with the base relic weapon and it's non glowie bits? I personally prefer looking like a bard again over doing a little bit more dmg(and hey af+1 is still far and away better than dl), if Twin was actually doable then yes I'd rather be able to pump out as much as possible but Square seems fairly fine leaving it as is till 2.1 where they may or may not address the fight so people can kill it.
