I can't say I ever noticed a "bacterial funk smell" on wooden boards. According to e.g. https://pubmed.ncbi.nlm.nih.gov/31113021/ https://pubmed.ncbi.nlm.nih.gov/31113021/ "Bacteria inoculated onto Plastic blocks were readily recovered for minutes to hours and would multiply if held overnight. Recoveries from wooden blocks were generally less than those from plastic blocks" Now, I wouldn't put too much stock in a single study like this, as it only tests a single bacteria under a limited set of conditions for starters, and when cleaned thoroughly it probably doesn't make too much difference. But in reality people are lazy, in a hurry, etc. and don't necessarily clean and scrub properly. Either way, I certainly wouldn't just assume plastic boards are more sanitary (ignoring the microplastic issue).
