I used to have my own Cabinet Making business with a production staff of 20. All my benches had Yellow Tongue bench tops. It's flat, it's strong. It's durable. Perfect for the job.
Obviously if you want to do a heap of welding then something else would suit.
I used to lay 12mm MDF over the work stations though as they got a workout and would swap them out every year or so to freshen thing up. Production runs are a little more demanding though.
