You’re thinking of the wrong Johnston, KB- the Fabian tactic Johnston was Joseph E Johnston.
In contrast Albert Sydney Johnston was regarded by Jeff Davis as his finest general. In fact Davis said that Johnston’s death at Shiloh was the turning point of the war.
Albert Johnston had a career as a Texas Republic general, a US Army general, and a Confederate general. He was the first commander of the famed US Second Cavalry that fought the Comanche. One of his field officers was Robert E Lee, who followed Johnston as commander of that unit. Albert Johnston was much like Lee and had he survived to command the western armies the Union armies in the west would have had a much harder fight.
Hardly a ringing endorsement. Davis thought that Braxton Bragg was an fine general, too.

We will never know for sure. Certainly Albert Johnston had all the potential to be a fine general; but then again so did the other Johnston. But since he was killed in his first major action then his true value as an army commander will never be known.
