In the long run, Normal STR should be the best with the least cost. If you do Low-STR, you'll constantly have to adjust your base STR as you upgrade your Overall and Cape whereas scrolling for DEX allows you to have a set base that you never have to change due to gear. STR-less fails for the same reason it fails for Bowmen.
EDIT: Although I did say normal-STR, the prudent person would still plan on getting a zhelm and HT/Deputy pendant and allocate STR so that they can wear their desired weapon only with those equips. Adding enough STR to wear the high-level stuff without those items is just stupid.
