The A005 is a good tyre choice for SE England for sure, you’ll be happy with them, no doubt.
This topic (and I think the actual video the OP has shared) has now been covered quite a few times but always good to revisit:
When I looked at what was available on the all-season market, I thought from the test data it has relatively high rolling resistance compared with some - which is incompatible with my aims for Merlin as a long distance eco express. There is also there no data available on how it performs in different temperatures and also when say, half worn.
The Michelin’s have been tested at different temperatures in Tyre Reviews’s video on the subject (this put me off the the Conti AllseasonContact as my preferred choice, as that tyre’s performance degrades by a fair margin in warmer temps; shame as it has very low relative rolling resistance) - also Michelin are THE best known tyre brand for worn tyre performance. They are expensive though, however this can be offset to some extent by their high durability in service.
For all these reasons, my conclusion was that if you have decided you need all-seasons, can afford them and can be sure you’ll get the wear out of them before they age-expire, the CrossClimate+ is still the safest choice. Concerns about ride comfort due to the much-higher-than-spec XL load rating have been disproved by esteemed members on here who run them, such as
@Edwrai and a few others, who say they ride comfortably once the tyre pressures are set correctly.
If you can’t quite justify the expense then I would look at the Conti, Bridgestone or the latest Goodyear. I would not go even lower class premium (Vredstein, Nokia etc.) for all-seasons as their performance just doesn’t stack up.
