Do you have a thick, heavy, or wiry beard, or would you say it is more whispy and light?
Reason being, many with very tough beards like heavier blades. That said, properly honed, either will be so sharp that they should make light work of anything.
Some like highly hollow blades for their flexibility as they seem to conform to your curves slightly.
In the end, it is all about preference and once you develop straight shaving skills you will likely find great results with either...but you may have preferences. It is sort of like knives...some guys like heft, other guys like thin flexible blades. All good, just different.
