I would rate it this way:

1. Artillery: Without question Union artillery was superior in every way. It was feared by Confederate Infantry for good reason.
2. Cavalry: Confederate Cavalry was superior, but waned towards the end.
3. Infantry: - tie.

General Jubal Early opined that the Union Artillery was much better than the Confederate at longer ranges, but that at close range, in tactical support of combat operations, he thought the Confederate Artillery far superior, more mobile.

To judge from his memoirs, Early was an immensely practical, reliable, and honest reporter. In fact, General Lee depended upon his notes and records for his own memoirs. For example, Early credited the Union Cavalry for the improvements he saw it making during the war.

One thing you'll get from his memoirs was the terrible burden material shortages caused the Confederates. Not only were their resources fewer, but their systems and supply personnel were very weak at the top. The Confederates worked their amazing successes on the field with empty bellies!

Cavalry: Confederate Cavalry was superior, but waned towards the end.

They were like the Japanese naval aviators in World War II. Once the experienced ones got killed, there was no one to replace them.
