Inverted V antennae are not so bad. I tend to agree that a full wave
loop is a bit large at CB frequencies to manage, doable if you have
patience.

+2 meters antennas are small, portable and get good gain.

Quite true.

First impression on this statement makes me a bit weary as to its
validity as a general statement. Especially if you are considering
line of sight communications.

In a more specific case it may very well be so. Trying to make a
general statement that "x" power output at "y" frequency yields better
distance than "w" power at "z" frequency may not always be true. The
major effects on communication distance is determined primarily by
transmitter and reciever antenna hieghts. Given equal antennae hieght
for both bands, and equal gain, then one can better compare distance
versus power.

It maybe true in your case. It may not be true in all cases.
