Kitchen Sink Soap Dispensers - Does anyone really use them?

Picking out new kitchen sink/faucet and wondering about the auxiliary soap dispenser things. I have one now and never use it. It’s poorly made/installed and it kind of wobbles and twirls around. I don’t see why someone would use it for dish soap - wouldn’t you want to put the dish soap exactly where you want it (on dishes or in dishpan)? So is it more intended for hand soap? Also what are the qualities of a “good” soap dispenser? I would think one with a long spout would be one but anything else??
