Need help to evade censorship (DNS based I believe) in multiple networks with Trisquel 8

Hey everyone!

So, I sometimes have the need to take my laptop with me and use it in different networks, with different ISPs. Unfortunately, in my country we have censorship in place, which happens to differ from ISP to ISP (I believe they were all supposed to block the same websites, but I have noticed some differences, even noticed that it depends on which day I try to access a certain website in a certain ISP). So either way, I have read other people who say that using Google DNS they can access these websites, so I suspect it is merely DNS based which redirect queries for these websites to a page where it says that the Government has blocked that page on national territory.

Usually I would use Tor, actually I only recently noticed these blocks because I always use Tor, but when latency is an issue (also speed, but Tor is quite fast, problem is latency I notice), I need to use clearnet access, in order to have the ISP full speed available. What I need is to know how to get around the DNS block, in a way that is secure and private (at least as much as possible). I have read some stuff here in the forums, about OpenNIC and DNSCrypt, but I got confused as to which would be best for it. I need something that is easily changeable in case of need, so a GUI solution would be nice, if not something that I can automate with a script.

Any help greatly appreciated and sorry for the long post. THANKS EVERYONE!
