These global industrial butcher block tops are what we use for our mechanics at work

They hold up to a hell of a beating and most are still being used that are 10 yrs old or more. Not bad priced either.
I personally don't like metal tops for tearing into things because stuff slips off, Mars your surfaces, and it's noisey unless it's 1/4 or thicker.
I actually priced some and once I pay shipping I could have 1/4" bent how I want it for a similar price!!!
I don't mind thinner metal tops for stuff. I plan on having it bent all the way down the lip of the table so it should be nice. But lots if other stuff first
