Which websites analysis of DNA matching is more accurate?

AncestryDNA: 151 cMs across 12 segments; Confidence: Extremely High


GEDmatch: Largest segment = 60.2 cM; Total of segments > 7 cM = 281.4 cM; 11 matching segments

I am curious as to which one is the better one to base my DNA confirmation statement on?

I tested with 5 companies in 2017. I like what they all present. I don't place one above the other. They all have their own regions they focus on. I love being in all 5 databases for the future and possible new things that arise or finding more DNA cousins to break brick walls.

Here is a great article about the 5 companies I tested with last year:  https://mashable.com/2018/02/02/which-dna-test-is-best-ancestry-23-and-me/#HTeSYxyBxiqq

If you are not sure, go with AncestryDNA as this is less tunable. A complete answer requires more info, e.g. what kind of kits are you comparing on Gedmatch and what versions are you comparing on AncestryDNA. If you’re comparing the very same kits imported into Gedmatch it’s not a matter of better it’s just different and you could probably tweak the parameters to get similar results.
