I’d say Virtualbox should be a good fit. I’m using it myself, mainly to quickly set up VMs for trying out new stuff, most recently Kubuntu and Manjaro distros.
I don’t know UTM. I’ve used Parallels before but it’s just not worth the cost for what I need it for. Then there’s VMware of course, which apparently also has free licenses for personal use. But since I’m happy with Virtualbox, I don’t think I’m going to use anything else anytime soon.
At work we have both, Edge and Chrome, and there actually are minor differences (that might well result from differences in the pushed settings, though). Like, when using our ticketing system, Edge loses the connection to the server after a period of inactivity and Chrome doesn’t. Also, Chrome seems to be a little faster with script processing (subjectively, have never measured…). But otherwise, they’re basically the same, just as you said.
