You need to choose a PIC with a Analog-to-Digital converter unless you need to add an external one. So, reject the 16F627. 16F88 is a nice and cheap replacement. I no longer buy new stock of 16F627A or 16F628A.

16F872 will work, if you have it on hand, use it. Unless we could still suggest you tons of other models. Just tell us how many I/O you need.
