I think the ton of requirements--most of which would be useless ("I sudden maximize my single magic missile!" "Oh, have mercy! Don't deal another five points of damage to me. Don't throw me in the briar patch!") are enough to keep this from being useful and even if you're willing to live with them, Sudden Quicken only works a few times per day.
In any case, look at the opportunity cost:
A fighter archer will want:
Point Blank Shot, Precise Shot, Rapid Shot, Weapon Focus, Weapon Specialization, Manyshot, Improved Rapid Shot, Greater Weapon Focus, Improved Critical, Greater Weapon Specialization, and Improved Precise Shot by level 12.
That's enough that a non-human fighter only has one feat left over and even a human fighter only has two other feats by then.
A non-fighter archer will cut that down a bit and probably have:
Point Blank Shot, Precise Shot, Rapid Shot, Manyshot, Improved Rapid Shot, Improved Critical, Improved Precise Shot
That's every feat until 12th level except for one for a non-human ranger. A human ranger only has two free feats. Nonrangers have to give up at least one of those feats, even if they're human.
In short, taking more than one sudden metamagic feat is likely to make the character a worse archer.

Wouldn't Sudden Quicken also work? Eventhough it's a ton of requirements, you don't have to keep taking levels in Wiz.
