I am reliant on other casters, varnishes, or enchantment to acquire EB for my bow. This, alongside HiPS (which I can likely see through), is the largest edge the Ranger has over me: ready access to a +5 EB, full BAB, and +2d6 Divine against their favored enemies (which will probably be Undead, Outsiders, Humans, Shapeshifters, and a flavor fifth - maybe Elves, if they really hate Drow - and so can be considered to be active against "most" enemies).
An Arcane Archer will usually do more damage and always have higher AB than them and absolutely, always should. It's the entire fantasy of the class.
A feat fighter does more damage and has more AB in most cases than all other archers, only eclipsed by an AA that manages to hit the +20 AB Cap (since their Enchant Arrow is outside the cap they'd have more AB, but with one less attack will have much less damage), but is absolutely miserable to level, has odd uptime, and has zero quality of life (stealth, utility, will saves). Though, they can also pick up any weapon in the game and be reasonably effective with it, as well as durable.
What I have over them all is full 9 Circle casting with some excellent party spells (including ones that, until Voodan, were unique in Big Sky) and some of the best enemy control in the game. Yeah, I'm not the strongest archer - but Druid shouldn't be the strongest archer, or honestly even close. My utility and DCs are exceptional, I have excellent capability to spot (even before using Hawk's Vision, which has an exceptional duration), and I have the ability to turn into a form if I'm forced to melee. I also have Premo. These are the same things Druid has over other frontliners - it is at its core a caster that can competently fulfill other roles, not an exceptional example of those other roles that happens to have casting.
