Basically more everything. 2x Cortex M33 cores with floating point, 520KB ram, more PIOs, bunch of secure boot stuff (I have mixed feelings about this), and can boot to a mode with risc-v cores instead of the M33s.

They tried, look at the TI Launchpad boards. They are still around but less emphasized now. Some of them are actually pretty nice, or were during their day. The originally MSP430 one sold for a long time for $4.30 and later ones were in the $10-20 range depending.
