The benefit of Repeater Gloves basically counteracting the penalty of Aim sustain (remember, Aim provides not only crit chance, but also attack, damage, and armor pen) makes it worth it over the crit damage bonus of Red Jenny Seekers.
As for the choice of helmet, it is really up to you depending on situation. Remember again, more attack rating is useless once you are hitting all the time already, especially on white mobs, not to mention the "Rapid Aim" property on Armsman Tensioner helmet is wasted once you start using Repeater Gloves. On the other hand, not hitting all the time may make attack rating a priority over critical chance, depending whether archer criticals in DAO uses double-roll (i.e. hit chance is rolled first, then crit chance rolled next) or single-roll (i.e. part of the misses may be missed criticals, meaning reaching 100% hit is almost always a priority over stacking crit chance).
Of all available helmets, the best one for an archer is pretty much the Helm of Honnleath, but I assume you plan on using this helmet on otehr characters as it is pretty much, arguably, the best helmet of choice for almost any non-mage builds.
Another feasible choice of helmet for an archer is actually Corruption, the massive helmet you obtained kinda late in Origins. Using massive helmet will not reduce your attack speed, only massive chestpice will. Stamina penalty from fatigue is also less of an issue for an archer as you are not going to be spamming talents as an archer anyways, as most archery damage talents may actually result in reduced damage over autoattacking.
