So I'm asking all the repeater Guru's out here
which to buy: Super StationMaster OR DB 224 Anteena?
I want to put it on the very top of tower.
Which is better gain and less noise,etc.

You left out a third quality manufacturer... Andrew; certainly the
equal of the other two above.

As far as your choice of antennas, price aside, I'd take the DB 224, or
equivilent (the other two vendors make this kind too). Its advantages:
physically superior to wind and ice, equal omnidirectional gain compared
with the station master, but you can easily configure the pattern to fit
your needs, such as a 9dB lobe, or a figure 8 pattern, etc. The station
master without physical support of the top is known to have internal
connection failures when exposed to severe wind. The DB 224 doesn't. The
DB 224 also has superior DC ground for lightning protection over the
station master.

Those are my thoughts. You'll see a lot more of the DB 224s in Canada
and in other extreme weather environments compared to here in the U.S.
