So I am looking at either the Bell & Carlson Adjustable Cheekpiece Medalist Tactical style 6 or the Varmint Tactical medalist style 2. Besides the adjustable cheek piece, the only real difference seems to be the forestock. The style 2 looks flatter and possibly wider/bulkier, where the style 6 is rounder.

So my questions are:

In what cisrcumstances is the rounder front end better than the flat? (Or is the rounder front better)

Which do you prefer (and why)?
