I find that unlikely, probably the Baltic Europeans, who have more European hunter-gatherer (WHG + EHG) ancestry, have more Neanderthal ancestry on average (the difference must be almost negligible, though, as the average variation in Eurasians usually range from 2% to 4%, not much then). Basques are one of the European populations that have best preserved the EEF ancestry of Late Neolithic Europeans, so they certainly must have much more WHG than the first, still almost unadmixed EEF, but it's still in the minority, and the ANF (Anatolian) part of their ancestry had a very significant proportion of Basal Eurasian admixture (i.e. non-African but lacking Neanderthal/Denisovan ancestry).
