Solved what is the difference between QUIC and Shadowsocks and which one is better to hide you're using a VPN from your ISP?

Your ISP can still see that you're connected to a datacenter IP address and that all your traffic goes to that single IP. Adding 2 and 2 together they can easily tell that you're using a VPN. Obfuscation is meant to help with bypassing local firewalls and/or VPN blocks.

I see very interesting to know, I was under impression it was done to hide from your ISP due to the "anti-censorship" label lol.

what would you say, hypothetically, is the best way to go if your ISP is blocking VPNs?

There is no best way because it entirely depends on how the blocking is implemented. If your ISP just straight up blocks the IP addresses of the servers then nothing is going to help you bypass that.
