I love STW sometimes… A thread about what chopping board to buy turns into a debate about how to store eggs!!
But back to the original question..
‘Plastic’ ones absolutely fine, if you are in a tight budget but if you want a nice looking one… End grain wood is the way to go.
I’d probably rather use a good plastic one that I can throw in the dish washer than a cheap crappy wooden one, just from a practicality view more than anything.
I don’t have a dish washer though and I prefer the aesthetics and ergonomics of a good quality wooden one.
