I was considering Whonix but Tails suits my case better as I won't need storage and forensical evidence is literally none in Tails compared to Whonix so it seems that fits my case better. I don't need security in the host as there won't be sensitive information on my system. Does that make sense? That's what I got from superficial research - correct me If I'm wrong.It doesn't make any sense to use VPS instead of a VPN if you are trying to hide your identity, some vpn providers proved in court that they do not keep any logs, so couldn't help in the investigation, I see no reason to use a VPS in this case.
I'd recommend (VM + VPN + TOR) to the OP
