Proficiency with an Exotic Weapon and Exotic Weapon Proficiency.

[Xenrac]

If a character is given Proficiency with an exotic weapon, do they get the Exotic Weapon Proficiency benefits for that weapon?

For instance, can a Kensai select either a Katana or a Bastard sword as his one favored weapon type and use it as a one handed weapon?

[blackbloodtroll]

Yes.

They are functionally the same thing.

[Starglim]

The two phrases in your title mean the same thing, apart from the way you obtained the ability.
