STM32F4 can currently do 8x8 sequential with speeduino FW so there is that. It also has built in SD card support, so getting SD-card logging to work should be easy. There is also RTC, so you can have time/date to SD-card logs, which is quite crucial to have, if you have constant SD-logging in use. There is also integrated CAN bus so communicating with other CAN devices becomes a lot easier. And yeah it's also lot faster, so it can do more calculations and be more accurate in the same time compared to mega. And after 8x8 sequential, there is still leftover timers to have general purpose PWM outputs. These are all features that I plan to take advantage on STM32.
Teensy can also do lot of those too, but the pin numbers available on Teensy boards is quite limited. Also it's pretty much closed source and you don't have free access to bootloader etc. that you have on STM32. Which I think is big plus to STM32 compared to Teensy.
Currently, I'm personally working on this thin, which should be drop-in replacement for arduino mega, if I ever get that finished and/or working. I won't promise anything
