I raced my TR4 in the Midwest for 12 years with an overdrive most of the
time.  I did use a regular 4 speed for a short time but didn't like it as
well.
The only problem I ever had was a few gasket leaks and having to change out
the solenoid two or three times.

I was on a pretty slim budget in those days and wasn't able to keep up with
the fastest cars, but I wasn't the last on in line either.

As a matter of fact I'm rebuilding my car and plan on putting the overdrive
back in.  It was really handy in a lot of turns where you could split your
gears and not have to shift all the way to third or fourth depending on the
corner speed.  You also had the fourth overdrive to utilize on the
straights.

 I never have run a close ratio gearbox, so I don't know what they are like.
But from my own experience, I really do like the overdrive.
