(comparing ARM and PICs)
> C compiler price?

gcc for ARMs, both C and C++ (and a few other languages) is free

others exist (commercial)

What's the difference when the bootloader is built-in? There is even an 
LPC17 chip with a built-in USB bootloader!

At least there is a standard...

If it is just for bootloading 5 pins should be enough

definitely the LPCs, but

- no DIP chips
- all 3.3V no 5V
- much lower output current (1mA IIRC?)
