Which is the best way to connect..

[dtit]

pi2pic when they are on same PCB and using two pins to communicate between them, and have one executing a task when reciving a message from the other pic.
ex. 16F877->16F628
message something like "do your B.0=1, B.1=1,value=168"
which method should a use, there are so many, read so much that it just confusing me more and more.

Connect two Basic Stamps together in a Master-Slave arrangement.

Both have internal USART. Connect TX from F628 to RX of F877, RX from F628 and TX of F877 together.

After that you can send a kinda *formated message* . something like that.

F628:
-----
HSEROUT [Var1,Var2,Var3]

F877:
-----
HSERIN [Var1,Var2,Var3]

Every VAR can be a specific task. You'll have to play with them with some IF THEN or SELECT CASE.

Works also without USARTs. See my post with the example for Basic Stamp 2.
The Basic Stamp 2 commands "Serin" and "Serout" are similar to
the PicBasic Pro "Serin2" and "Serout2" commands.
(One optional pin is used for the flow control).
