Hello. Tor is blocked in my country. I can only use two ways to connect to Tor:
ISP -> obfs4 bridge > middle node > exit node > siteISP -> VPN -> obfs4 bridge > middle node > exit node > siteWhich one should I prefer? Does VPN before Tor makes me safer or just slows down the connection?
Using a VPN to connect to Tor is rarely if ever advisable.
You are basically connecting to a permanent guard node which is a single point of failure.
It may obscure the fact that you are using Tor, but it would make your connection much less secure.
ISP → VPN > middle node > exit node > site
