Ugh, Userbenchmark shouldn't even exist. When Intel was being thumped by Ryzen, they reconfigured their test to ensure Intel returned to the top. So no, don't trust it. Cinebench R20 is a decent CPU benchmark, and one the reputable review sites use as part of their standard suite of tests so you can compare it against theirs. 3DMark also has their own CPU test you can use to compare against all the submissions online.
This alone tells you how useless that site is. Their "best" list is all entry level to mid range hardware. I used to use it as an at-a-glance comparison for the less tech inclined, but it's a joke now. Anyway there's a thread on here, Post Your Cinebench R20 Scores Here, you can use to also have some additional points of comparison.
