I'm not so sure about the "reasonably" priced on the 75/25. Around here
it costs double the straight C02 and lasts half as long so the 75/25
costs about 4 times as much to use.

The local fabrication shops use the 75/25 mainly because of the C02 is
not as pretty and you get more splatter around the weld. I use the C02
because it is so cheap and according to the tests I've seen is just as
strong. I'm not into pretty (rusted sculptures) and with using the
welders, Lincoln and ESAB a lot every day the cost saving is
substantial.

Anyway, there is a shielding gas comparison at:

That is a brief article but has a link to a much more exhaustive test.
