font face in fvwm vs cwm

Hello,

I installed a snapshot of amd64 recently and I was using fvwm from
Openbsd base to install some packages. I even started Firefox to look
for some documentation.

Later, I was going back to cwm since I use it daily. I have a feeling
that Firefox pages fonts in fvwm were more appealing that what I see
now in cwm. Is it just my imagination?

Let's say i will go back to fvwm, but I see there is one fvwm in base,
shipped by default, but there is also a package called fvwm2. Could
you give me some recommandation for one of the other, please?

Thanks.
