Like Andy said, ease of cleaning = a run through the dishwasherI bought a plastic cutting board several years ago, and found that it had deep scratches from my knives after a few uses. Ease of cleaning? No, trying to clean the cuts, even with a bleach solution, was more trouble than just washing the wooden boards.
Your dishwasher will totally sanitize plastic boards.
Like Andy, they are almost all I have used for 40 years even though I have 2 very lovely and expensive wooden boards (gifts).
That said, people’s choice of boards is a personal one. But cleaning a plastic board shouldnt weigh into the decision if you have a dishwasher.
