I was looking for a general purpose Cortex-M4 microcontroller for an automation project.

After a quick search in Farnell's site I noticed that some Microchip's micontrollers are rather cheap from STMicroelectronic's chips.

To be exact:
I found ATSAM4S4C at 2.57 GBP at 100 pieces. Which is powerfull enough with plenty RAM and FLASH memories.

I also found the STM32F303RDT6 at 3.01 GBP at 100 pieces. Which is slightly expensive.

The question is what is the difference between Microchip's ATSAM and STM's STM32 microcontrollers and why someone would choose the one instead of the other?
 

I used STM32F0 series. Was less than 1$ per each.

STM's chips prices has gone up a little. I think they were significant cheaper. Weren't they?
 

Assuming this question is serious (and not an attempt to start a flame war) then I can think of 2 answers.
The first applies if I was doing a personal project in which case I would chose the one that had the more memory and peripherals and not be too worried about a few pennies/cents/<insert your favourite currency here>. Also I'd lean towards whichever device was supported by the development environment I had the most familiarity with.
The second applies in a commercial environment where I would be looking for the device with the least memory that satisfied my requirements and had the least number of unused peripherals but still had the best footprint for automatic PCB placement and the lowest unit cost. (In this case I would probably not be looking at the 100-off price but for the higher quantity breaks.)
In short, it all depends on your circumstances and requirements.
