For all performances I use a headset mic. I enjoy the freedom and having nothing between me and the audience which enables eye contact, gesturing, smiling, etc. Mic technique is different but doable. As others have noted your mouth can be turned to one side and I've learned to “swallow” my voice and also minimize breath noises. It just takes practice.

I have used a Crown CM-311A headset mic for the last 12 or 15 years and find it best for me. Sometimes I use a wireless adapter as this mic has an XLR connector on the battery/control pack. I tried many others including expensive Shure and Countryman headsets and found them too prone to feedback and plosives including cartioid polar patterns.
