I have a lot of family around Seattle and have visited frequently. One year I visited in May and it rained nonstop, oscillating between a soft drizzle to a torrential downpour, for 10 straight days! Too depressing for me.
Boston: 43.76in / 137 days
Seattle: 34.1in / 152 days

Hours of sunshine during winter months (Dec + Jan + Feb): Boston: 464 Seattle: 235 (-50%)
Annual hours of sunshine: Boston: 2615 Seattle: 2019 (-23%)
so it's accurate to say that Boston is sunnier than Seattle and much sunnier during the winter.

137/152 are the number of days w/ precipitation, not sunny days. ie, Seattle has less rain, but more days of precipitation. This is typical comparing Seattle with many other cities: less rain total, but spread over more days.
Those more days are concentrated in winter, more so than in is typical in other parts of the country. If you look at the "hours of sunshine" stat over a whole year in your links, the typical seasonal change people complain about in the PNW is right there: Apr - Sep are similar, but Nov - Feb Seattle gets half as much hours of sun.
The concentration of gloomy drizzly days in winter is quite real.
Rain in May is a bit weird (only 1.9 inches on average according to wiki), torrential down pours in Seattle are even weirder, especially outside of October/November.
EDIT: Ok, I get it...I get it.
Personally, I think the whole 'Seattle has horrible' weather is pretty overblown. It's grey for a couple of months.
I'm writing this now, in February, to a perfectly blue sky. It is cold, but not grey in the least.
I've personally found it more challenging that folks don't seem to socialize much. They just work non-stop throughout the week, then perhaps do something on the weekend. It contrasts quite a lot to when I was in New Zealand where you frequently see your friends after work.
More sun is great, but I prefer regular drizzles at 40F to a clear sky in the single-digits punctuated by massive blizzards.
New York: aggressive aggressive
Seattle or Vancouver: passive aggressive
Well I guess fire is a kind of chaos itself.
