What brand of taps do you use?

For most applications I use the standard Greenfield taps from MSC. The relief style are nice for deeper holes. It prevents tearing the threads out of softer materials when the tap is reversed.
Emuge is by far the best tap in the world, hands down. I use their high helix 3-5 flute relieved style, CNC taps for all the tough materials I tap. They are made for CNC machines and have little lead. It takes getting used to them for hand tapping. They also cost big$$$ but I am friends with a tool distributor. I only have Emuge taps down to 4-40 so smaller than that I use the Greenfields.
MSC has taps now thay they claim are for Titanium but I would have to pay full price for them so I will stick with the ones I have now!!
I feel that the most important thing about tapping Ti. and other tough materials, is nowing when the tap is TOO dull and retiring it BEFORE it breaks!! Taps have a lifespan. More expensive taps have a slightly longer lifespan.
