As usually what one thinks best and all vision about sailboat preferences has to do with personal and subjective tastes that are revealed by the type of boat the one that is talking (or writing) about has.
The author of that article owns a Mason 44 a 35 year old design, a full Keller and a very heavy boat (382 D/L)

This explains the opinion of the writer in what concerns the article and general point of view.
We have a
member of this forum that had for many years a Mason 44 that he sailed extensively
offshore and that substituted, some years ago, by a modern
bluewater boat with many of the characteristic the writer of the article considers not good for comfort or
safety: a beamy boat, a light boat (182D/L) and a fast boat if compared with the Mason.
Steve's opinion was that his new boat was a much better offshore boat than the old heavy Mason in all aspects.
So nothing wrong with the article if your preference goes to heavy old designs but not much to learn about if you prefer modern or fast performance bluewater boats.
Regarding those preferences in what regards sailor's average tastes, they are expressed on the market by the offer and you can see that boats like the Mason 44 are not built anymore. No offer because the ones that would want them is much more reduced than even the number of guys that prefer very fast, very light bluewater boats like the Pogo or the JPK (there is a considerable offer regarding these boats).
The Average will want boats like the
Oyster or the Halberg Rassy that today are medium light fast boats with all those characteristics the writer dislikes.
Besides the article is not about (as you say) :
"what is the best sailboat for me?"
But about how to chose a bluewater boat and there are very few that make bluewater sailing their preferred type of sailing. 99% are coastal sailors that eventually make some offshore passages and eventually cross oceans (for doing more coastal or island to island sailing).
For 99% of the sailors a boat fully adapted to bluewater conditions will not be the best boat. For almost all, the boat that makes sense would be a boat designed to be very good in coastal conditions (that allows to enjoy life and a has great living interior) that has also the capacity to sail offshore and cross oceans from time to time.
Compromises in what regards design are different regarding the two goals and most modern boats, the so called main market boats (big production or not) show the design compromises I had talked about on the paragraph above, the ones that suits most sailors.
Also most of the sailing and cruising is done where the conditions are nicer to most, warm climates like the Med or the
Caribbean or somewhat protected waters like the
Baltic.
For the 1% or less, that wants to sail in high latitudes, or during the winter, the choice of boat would be different but then we would be way out of the
"the best sailboat for me?" since "me", as a generalization, would refer to those 99% and not to the 1% (probably less) that want a sailboat to sail offshore on cold high latitudes.
