Not so easy to answer ..... in the micrcontroller arena you have to select what you need according the target application so you have to look at some parameeters available on datasheets:
Architecture (Harvard/ Von Neuman)
Pipeline (yes/no)
Type (8-bit,16-bit,32-bit core)
Performances (DMips / CoreMark benchmark)
Operating voltage (low voltage / 5V)
Operating temperature (up to 85C, 125C or 150C)
Low power (YES/NO current consumption in stand-by < few hundreds nA)
Numer and type of peripherals, interrupts, ....
Developement tool (free or not)
Memory cycling/retention
.....
As you can see it's difficult to say! I think nobody did this comparison, anyway a micro can be better than another for some of these parameters and vic eversa. Also the price can make the difference. If you collect all these infos for all the micro you mentinoned perhaps you can have an idea o what you're asking.
good luck
