I wonder if the GA pilots normally listen to 121.5 MHz given you have two COM radios.
Is that a good habit tuning Guard into your second radio?
Yes, I do. They called me once on an IFR flight when I selected the wrong frequency and also forgot to check in with them.
Always outside of Continental Europe and pretty much always within Europe if the primary frequency is quiet.
What does Guard mean?
Are you sure every G/A plane has 2 com radios?

Guard: a state of caution, vigilance, or preparedness against adverse circumstances; watch over in order to protect or control.

I do if I have the option to monitor a second frequency.
Not normally, unless (sometimes) flying over very remote areas w/o ‘normal’ radio contact.
Always on any (non-trivial) IFR-flight. Lots of things can go wrong with the primary radio 
I very often have it on as my only radio frequency; if I am away from controlled airspace and have no particular need to talk to anyone, it’s nice to get the peace and quiet.
That’s why other people misusing it is a pain.
