Actually, in the last 4 years, not much has changed at all other than certain models having dropped out of production and new models have entered the market. Telescopes are a lot like airplanes, cars, and many other things. You can design one that does everything acceptably, but to do one thing very well, there are trade-offs in other areas. I'll never take a stand as to a certain telescope being "the best" overall. Each type (and brand, actually) has strengths and weaknesses. I love all telescopes, taking each on it's own merits. I will never make the statement that a certain type is best. Like you, I have a fondness for doublet refractors, but I'll defer to a huge mirror when going after faint deep-sky stuff. The only APO's I'll ever own are ED doublets. I'll buy a triplet when I hit the lottery. But even non-ED refractors have a certain mystique that I am, for better or worse, a sucker for.
