The SM58 is the universal live vocal default. The Beta 58A is its hotter, brighter cousin. Both are made by Shure, both are dynamic, both are used worldwide on stages every night.
If you sing classic rock, jazz, country, or church: get the SM58.
If you sing loud rock or metal and need brightness: get the Beta 58A.
If you struggle with monitor wedge feedback on stage: get the Beta 58A.
If you need to outfit a venue with 12 mics on a budget: get the SM58.
If you don’t want to think about it: get the SM58.
