Both are great and will last, especially the classic moctoes. Thorogoods are a little cheaper and have a synthetic welt, while the redwing moctoes are totally traditional all-leather and cork.

The synthetic welt eventually does crack if it's old and bent enough times. A leather welt won't crack if it's regularly conditioned.

Thorogoods are better for work simply cause they're cheaper and will also last just as long as redwings if you really work in them. For more casual use, neither will wear out but the welt might crack as it gets brittle with age (talking about 7+ years...).
