It would seem unlikely that there is any inherent superiority either way, as
the engine design is identical. More displacement should equal more power,
everything else being equal -- and in this case it really IS equal.
In this example you never had yours on the dyno, so it can't really be
compared. I suspect a Courier is lighter and has less frontal area than
either an A or B, so your impression may have been deceiving. Or you may
have achieved a higher state of tune than Eric's car has at present. But I
don't see any reason why your Elva wouldn't have been even faster with a
similarly-prepared 1800.
The twin cam would be a different story (to head off the obvious rejoinder).
