diffrent between PIC's

I want your advice to start project using PIC .what is the type of PIC i have to use and what is the diffrent between each others.

The type of project defines the PIC to use.... what do you want to control, how fast, space requierments, how complex?.

:arrow: To start I suggest you do the PIC16F628 which is like the 16F84 but better.
