choosing a holster??

[Franklin7X57]

I'm leaning toward a high noon iwb holster. They make several holster that are "alike" but different. The Tailgunner, the Down Under, and the Bare Asset are the ones I like. The Bare Asset for the price, the tailgunner and the down under because of the sweat shield and the sight track. My question is about the clip vs. strap and tail piece vs non tail piece? It's for a M&P 45 so it's a full-size.
Thanks.
