PULPino or PULPismo ? for a low-power microcontroller

[sit-vlsi]

Hello, We are trying to design a ultra low-power microcontroller for IoT applications in a 0.18um CMOS technology and I am trying to decide to choose the PULPino or PULPismo platform.
PULPino seems like the more matured platform but PULPismo seems to be the replacement for PULPino.
Our core strength is analog so we want a platform which has a well-supported toolchain, etc.
So any advice on this topic will be greatly appreciated.
