The 2mg Klonopin is stronger than the other 2 pills you mentioned. They are all in the benzodiazapam family and some prefer one type over the next but if you were only going to take 1 pill the Klonopin is the strongest. Now if it was a 2mg Xanax (which its not, its 1mg) then I would say it has a slight edge over the 2mg Klonopin.
