Chose for your application
If the bullets are cast and sized properly, they're pretty much going to shoot straight. From there, profile selection is mostly a matter of your application and needs.
For me, I'm a big fan of SWC's (or better yet, full wadcutters) because I mostly punch holes in paper. The truncated cones are better for action shooting sports because they speed-load easier.
But for my specific needs, I use the SWC's (or WC's), even in action shooting sports - I am willing to give up some speed-load time (very little, as my gun has chamfered charge holes) to get the nice sharp round hole in the target. Because my eyes are old, I need the large hole down range so I can see if I got the hit.
But all that is just me. Point is, pick the profile that is right for you. Most all of them are plenty accurate.
