What has been the better way to go for a spinnaker halyard/take down line and tack sheet?

I currently have it set up with a single line where it pulls the tack when raising the spinnaker. Someone had recommended that many people are going back to a separate halyard/take down line and a separate tack sheet due to the fact it allows for more adjustment. I like the current set up, but I have to agree with the logic.

Any advice?
