I guess my mind is on "What ifs", but it would have been more intelligent to handle Palpatine with both Obi-Wan Kenobi and Yoda. Anakin without any sort've head to his operation would not be a challenge for anyone. Obi-Wan actually defeated Anakin because of his arrogance, and stood up to him throughout the battle even with Anakin's anger fueling every strike. Obi-Wan at that point was stronger than Anakin and even handled Darth Vader in EPIV. Palpatine would have been the smartest target to point their two sabers at. Palpatine was the head of all the trouble. Handling him would have left no more problems down the Jedi's path.
