My 'MH' Ethnicity Estimate...
Irish, Scottish, and Welsh 78.3%
English 14.5%
East European 3%
Iberian 2.8%
Baltic 1.4%
I have Scottish & Irish on both sides but know of no Welsh ancestry to date although I know of relatives on my paternal side born in Wales which may have been taken into account with my matches?
I believe my English 14.5% is my maternal side only but the rest is unknown & not enough to have me curious/seeking them out.
My 'A' Ethnicity Estimate (which is broken down further on their site for you/us)...
Scotland 78% - Scottish Highlands & Islands - The Outer Hebrides
Ireland 20% - Ulster, Ireland - Tyrone, Londonderry & Antrim
Sweden & Denmark 2%
For me 'A' is 100% correct with my Scottish & Irish ancestry according to my own paper trail.
I find 'A' so much easier to use, find matches, compare, check trees, message et al.
MH is a complex site in my own opinion although others may find it ok.
My brothers' 23andme Ethnicity Estimate...
European 100% - North West European 100%...
"Northwestern Europeans are represented by people from as far west as Ireland, as far north as Norway, as far east as Finland, and as far south as France."
British & Irish 100% - Glasgow City, United Kingdom & County Cork, Ireland
The above doesn't fit with my research i.e. I have no clue as to how Glasgow City & County Cork fit in?
From the 3 I've picked out, 'A' results are more accurate to my own research & matches, the others are a bit vague.
I'd recommend you go on research & matches too but you need to consider NPEs.
