To keep weeds from getting snagged on it.

A weighted swimbait hook places the weight under the middle of the bait making it fall more horizontal. It also acts as a keel weight to keep the bait from rolling. The weighted jighead places the weight at the nose or front of the bait & it falls head first. Different actions.

so different actions and prevention of snagging

Correct.

so now i guess my question is when and where to use those presentations

A swimbait on a keel-weighted hook is remarkably weedless and may be used all the time.

If a belly-weighted hook wasn't exceptionally weedless, I would put it out to pasture  ;-)

To maximize weedlessness, I thread on a "1/16 bullet sinker" before tying on the hook.

The little spire-pointed sinker shields the eyelet of the swimbait hook, which is the only snag-prone part
