I do not like wireless, as there are too many variables (i.e. distance, frequency availability, frequency scanning, body pack antenna maintaining clear line of sight with the receiver, etc.).
If you want wireless, the Shure system is great, as is the Sennhiesser. You just have to make sure they transmit in the new frequency range, which has been narrowed significantly.
For wired mics, we use the Audio Technica AT2035, which is what we use for our front ensemble. You can also get wireless packs, and still use those mics as well.
