Run a simple model - then look at the patterns. That should help you
decide. As an alternative, you can look at using a quad. As I recall, it
performs as well, or nearly so, as a 3 element Yagi. It also has a lower
angle of radiation for an equal height. Trouble is that a quad is a
difficult 3D object, and may be prone to ice pick up.

I think a 2 el tribander will beat the pants off a G5RV on 10 15 and 20,
even at 25 feet. On those bands the G5RV pattern is complex, and the station
you are trying to work could be in a deep null.
I wouldn't get the Mosely though. I would get a Hy-Gain TH-2. N6NB did a
series of antenna comparisons, and determined that the TH-2 was a
surprisingly good performer for such a small antenna.
