well,from what I have learned is that an "anti-microbial" soap cleans infectious germs better than the ordinary "anti-bacterial" soap we are all commonly used to.I have been using a basic one like this for years and on many many tattoos and I have yet to get an infection,now I'm not saying it will work or is needed for everybody,but it has worked well for me. https://www.walgreens.com/store/c/walgreens-antiseptic-skin-cleanser-4/ID=prod6329601-product?ext=gooKBM_PLA_-_Health_Care&pla&adtype=pla&kpid=sku6276171&sst=84f55c5a-36b2-452d-b9c2-91888e50bfd5
a tattoo is a fresh skin wound and it just makes sense to me to treat it like any other skin wound.
"The primary difference between antibacterial and antimicrobial substances is the types of microorganism they act upon. While antibacterial products prevent the development of bacteria, antimicrobial agents such as alcohol-based hand sanitizers prevent the spread of bacteria, fungi, and some viruses. This is a much broader scope of protection than the protection found in antibacterial products."
now the soap I use is not a "alcohol-based hand sanitizer " but you get the idea. https://www.microban.com/blog/antibacterial-vs-antimicrobial

Is there a difference between antibacterial and antimicrobial?

this is just my opinion and preference.
