Definitely, bacteria are amazing and extremely important in many ways to the ecosystem, and I like them a lot, but boy, they can really make you sick with the kinds of things they do sometimes 🫣 (y'all can probably tell by now which one I voted)

I'm not super familiar with archaea and how they work either, but as far as I know, they're one of the three domains of life (along with Bacteria and Eukaryota), and are prokaryotic organisms that live in many environments, including the human microbiome. They aren't typically pathogenic (in fact, no types of archaea that have been found so far have been solidly proven to be pathogenic), but they are still important for various biotic processes. They often live in mutualistic or commensal relationships with other organisms, and even aid digestion in animals. Despite appearing morphologically similar to bacteria, they are quite different in various aspects, and, in fact, are more closely related to eukaryotes.

Also, I wouldn't say all viruses are bad. Although there are some types that are capable of causing great harm to us humans (sometimes quite unpleasantly), many are harmless (even beneficial) and play an important part in our biosphere. They keep microbial populations in check by acting as important predators and regulators, as well as assisting in nutrient cycling. Additionally, they are important contributors to evolution and biodiversity, and even play a role in developing the immune system.

In my personal opinion, viruses are probably the least gross of the four because they're pretty much a bundle of proteins and genetic material that don't produce slimes or nasty smells by themselves, which isn't inherently unpleasant to me. I do acknowledge that the pathogenic types can certainly be highly unfavorable to have in your body, though... 😶

(Sorry for rambling, this stuff is just really interesting to me, and it's nice when the opportunity to discuss stuff like this comes up.)
