I have the 148D and 158D Tayu models.
They are arguably the best dolls you can get right now. They are primarily designed for bedroom fun, the fact that they also look stunning is the cherry on top. They are also at the forefront of lightweight dolls with their silicone based soft foam cores. Usually the problem with cores, especially the soft kind, is the adherence of the silicone layer to the core itself, where you can have some delamination issues like on my D4E 160 silicone (which was made in the same factory than SM). Tayu has none of those issues. Speaking of SM, they also have some very lightweight dolls. While I have felt a couple inn real life (and they are soft), I don't know enough about them to comment.
I'm a big fan of Tayu but they are very expensive. There are other brands that are creeping awfully close to Tayu quality at less than half the price. Notably Angel Kiss and Zelex SLE line. The SLEs have a harder core and the thighs are much harder than Tayu. My new favorite brand is Angel Kiss where they offer hard hands and feet, moving jaw on select heads, implanted brows and lashes (upper and lower, where Tayu only do lower), and the silicone is SOFT. It's so soft, in fact, that I'm weary of leaving clothes that are too tight, or putting too much pressure while handling in fear of leaving indentation marks. So not a beginner doll, but neither is Tayu.
I hope this clarifies some questions you may have had and makes your purchasing decision somewhat easier (or harder LOL).
With that said, here are some photos.
