It would depend on what you were using them for. If you are just using them for general grunt work, and not thinking about sharpening them, they should do you fine. If you use them on a regular basis and like to keep a keen edge on all your bits, I would look for something else. The titanium and cobalt is just in the coating.
I have a set of Milwaukee's that I had for over 35 years and have supplimented these with general use bits from Craftsman, Chinese, etc.but my complete index of bits for 'good' use, is the Milwaukee's.
If you are doing drilling in 1/4" and under material, go for the multi- bit with four or five different sizes in one.
