Best AA is Clc15/brd2/AA23. Travel give haste so make it ez to pull mob apart nd DP give extra full BAB attack. Div dmg not resisted wen enemy wear archer belt.
Next best ED Rog 13/brd 1/AA26 hi-stelth for many sneak dmg. Take Called Shot feat for all AA. Rog AA does traps gud too so can pull mob into trap ez.
Harper give 2 Grt Dex for 5 epic lvls then stops. HS better for CHA build cuz only prestig class with Grt CHA for bonus. Asn AA better for DEX feats but evil.
Ranger ned too many levels to get BoE. AA get +1 Ab/+1 dmg for 2 AA lvls. FEs only add +1 dmg for sum race for 5 rgr lvls but not Ab so AA better archer.
People always trot out Level 40 builds, which essentially apply only on some online player worlds, which is almost never what the person is asking about. PW builds should be a separate topic, since they are subject to house rules anyway.
HotU and most other Module top out in the 20's, an here we are talking about SoU which tops out in the teens.
Also while Divine builds can work for Melee or Range fighter, a significant number of people don't want to have to buff up with spells to fight, and be hopeless when they run out.
I prefer a strength based Fighter/Bard/AA. At almost any level you can fight melee about 95% as good as dedicated melee fighter with AA on top. Very handy at lower levels when Archery is particularly weak, as would be the case in SoU.
