Tongue and groove is an interesting joint. I have used both the planes and the router table.

If you are doing a floor – router table
If you are doing short wood – router table
If you are doing longer woods or thinner boards – hand tongue and groove

The router table does not do well if the boards are not real flat. The hand version setup is done while the router takes a bit to align everything.
