That's assuming you have 0 backlash or your backlash compensation works perfectly as you move in and out of climb milling. I find I still get better holes with a boring head for slip fitting ball bearing races for example. But if all you want is a round access hole and the transitions aren't important then a boring tool is a lot of work compared to G-Codes. Now if I had preloaded ball screws on X and Y then I suspect the boring head will become redundant.
