The drawbacks with the blades is they are not very forgiving. As far as the hand held circular style metal cutters I have a Makita and love it. If you do a large variety of work I would stick to a long travel style drill, they are a little longer but much more usable. Depends on you main application, for production of the same sized holes in under 1 1/2' material I would buy the slugger style of drill with coolant. The slugger bits are awsome if you have a lot of the same sized holes but they cant cut thicker material. With the 3/4 chuck you can get any sized bit or hole saw. One big difference is the amount that they travel which makes the Milwalkee more adaptable for set-up. Hello, I have used both the hougn that was rented and we own a milwalkee.
