"Hypothetical" scenario for you all. You're speccing out a new machine and have a choice of either CAT40 or BT40. Both would be dual contact. You live in the US. You care about quality tooling. You use a mix of imperial and metric tooling. You have no other machines with either interface in the shop, so "get what you already use" does not apply.
What do you choose and why? (And is it even a debate worth having?)
