I think it is always better to buy the last version of Pixhawk because the idea is that the end date of support is futher away.
The Pixhawk 4 is old than the 6* version in addition the price is very similar between 4 and 6C
but the 6C is more powerful than 4

I leve here a little comparison among two board ( Pixhawk 4 , Pixhawk 6C )
