Berkeley and Oakland alone though have a larger area >15K ppsm than Westchester County.

Except your list doesn't have the amount of people living in each neighborhood.
Ran the numbers out. By people living in tracts above 20k/sq mile, Westchester comes out ahead, and even more so by %. But Westchester has a small % of its residents living at medium densities (5-15k per square mile). Here's the breakdown for Westchester County:
520,155 above density 5000
328,781 above density 10000
219,644 above density 15000
139,512 above density 20000
88,279 above density 25000
48,951 above density 30000
29,117 above density 40000
11,561 above density 50000
Alameda (which has about 1.5 million people while Westchester is just under 1 million):
1,160,046 above density 5000
629,764 above density 10000
260,961 above density 15000
132,248 above density 20000
64,820 above density 25000
32,704 above density 30000
8368 above density 40000
8368 above density 50000
I'd assume the low density tracts in Alameda County are east of the hills, on the hills themselves, are just drawn to include a bunch of non-residential land. Weighted density is similar for both counties, probably because weighted density gets easily affected by a few very dense tracts. Westchester 9,768 per square mile, Alameda is 10,108 per square mile. Interestingly, Staten Island has a higher weighted density than either of the two counties, but most of the population lives at densities between 9-20k/sq mile or so. Staten Island has roughly the same local bus ridership (94,000 / weekday) as Westchester despite having half the population. Some of the local bus ridership might be to the ferry, so might not be a perfect intra-county transit comparison.
