Bad news!
1. Iso burned on DVD isn't able to boot my old Toshiba laptop

2. Live session freeze directly opening Firefox, impossible to install lang package (french) freeze too
3. failed to install on 8Go drive ask for 12Go and installer is very slow if you want my opinion this OS is hell bloated
4. as I'm obstinate I decided to test the Debian + Cinnamon based version (
lmde-4-cinnamon-64bit.iso) as well => Not better
From here :
https://cdimage.debian.org/images/un.../current-live/
you can download hybrid-iso of debian including non-free drivers for hardware.
I choose
debian-live-10.5.0-amd64-cinnamon+nonfree.iso to give a try in the same VM to get a comparison between the 2 distributions.
First good point Debian's Menu offers directly language support,
opening the live session I get a warning message from Cinnamon telling it needs graphical acceleration otherwise it will suck cpu resources or something like that.
So at first glance Cinnamon doesn't look good for frugal hardware.
Debian Cinnamon comes with ESR and freezes directly.
Now trying with sister ISO Debian/XFCE everything works fine included Firefox ESR.
So definitely Cinnamon is the problem with a poor hardware.
Your choice should be to change Cinnamon for a lighter desktop environment
or to buy a more powerful PC with enough GPU to support fancy Cinnamon's stuffs.
Hope this will help you to make a good choice.
In your position, I would try XFCE (but as it is yet my favourite desktop so this is not a neutral advise ;-)
