However, after winning over an extended two miles and three furlongs on Boxing Day, Taaffe believes the Jewson offers the best chance of Festival glory.
He said: "The preference for Argocat at the moment is the Jewson over two and a half miles.
"He won't run again before Cheltenham but he has been in super form since his win at Limerick. He had a mid-term break and is back in full swing now.
"He did what he had to do at Limerick and was in receipt of the four-year-old weight allowance.
"He is progressive and has done nothing but please us since he has gone over fences.
"I started schooling him in April last year and he jumped so well that I said that we are better off going over fences than sticking to hurdles.
"Better ground will definitely help him a lot and that's why I have entered him in the two other races."
