Have used both over the years and on game rifles and prefer a bead, just slap it over the desired point of impact and squeeze. A flat topped post, or sourdough, gives a more precise aim point but is much slower for me just because as an old high power shooter, I'll use it as such. I am in the process of sighting my dad's old 721 .270 w/a receiver sight and a 1/16 gold bead and am quite happy with it. What you need to do is get the proper height bead and flat top and shoot both, its fairly inexpensive as well also now having a backup, and see which one is for you. Just make sure on a larger bore rifle that the bead is not too small. We generally have snow here in the game seasons so I use the gold (brass) bead but do really like the Ivory against any backround other than snow. The Ivory or silver shows up much better in low light than the brass if you have darker or neutral backround color conditions- Muddy
