Transmission comparison between C4 & AOD

I recently acquired a 1984 Thunderbird with a C4 transmission and was wondering how the C4 compared to the AOD from my 83 Cougar?  I want to make sure that my cougar which is going to be my primary transportation has the best option available.  I have no previous experience with either of them pros/cons so that is why I am asking here.  Thanks much.

The C4 is a non-OD transmission and (basically) a non-locking C5 which was the predecessor to the AOD. If I were to put one in a daily driver, I'd go with the AOD.

The stock 84 three speed  tranny is the C5.
