Which TPM 2.0 software stack do you prefer?

In my search for options of open source implementations of the TPM 2.0 TSS, it seems like there are currently are just these two main options:

It would be great to connect with anyone who is also working in this area and has some real world experiences working with either of these implementations, and with the respective communities.

I’ve not seen any other alernatives to IBM and Intel that anyone in the TCG community or elsewhere is working with. Please let me know if I’ve overlooked any implementations that may not be as popular.
