Confectioner's ring is basically Orvail ring minus the material loss which it hard to measure, so that shouldn't be the reason you pick an alt over your main. Other than that, really depends how organized you are and how much free space you have (are you a hoarder?) without craft ingredients.
There are two ring slots. You wear confectioner's AND orvail+1. Orvail competes with craft master's, so picking it gives success rate (probably not important) and material retention.
I have crafting ring on both my mains. I used to feel worse about it, but these days the other adoulin rings are much less impressive so it's not much, if any, sacrifice to take orvail
