The 2017 Survation poll was done by telephone rather than online, and methodology will have changed. We can't assume it will be the most accurate this time. In 2015, Survation had an unpublished telephone poll that was also the most accurate, closely followed by ComRes. Their 2015 online poll was the least accurate for that election.
We simply can't know which will be the most accurate until Friday morning.
