If good china sets off an appetizing dish as a shirt and tie set off a face, then the surrounding frame (table, linens, glassware, flatware, room decor) should harmonize and support the effect as a suit and other accessories do a well-cut shirt collar and elegant tie. Some meals will be more formal and others more relaxed, and the dining room "dress" should be able to adapt. I've always thought that a good plan was to have one service of classic plain white china, which can be dressed up or down to accommodate both simple fare and artfully composed avant-garde cuisine, one tailored service with restrained decoration (sort of the business suit of china), and one rustic/artisanal service (probably not porcelain), such as hand-painted faience, for outdoor or more exuberant ocassions.
Of your two choices, I would prefer the Wedgwood White. It could serve as the first of my three categories, and I prefer the classic round shapes to fluted or faceted ones for plain white, as being more versatile and a better platform for contemporary food presentations, but that's a personal taste.
Since Royal Worcester was acquired recently by Portmeirion, a number of their patterns have been discontinued and have been available at dramatic discounts. I'm using
this one for my "tailored" category (I prefer its can-style teacups, and it comports well with my art-deco era dining roon):
Unfortunately it looks as though many of the Royal Worcester patterns have been sold through in the U.S., though they may still be available in the U.K. I had to go to an English source for the demitasse sets for my pattern.
Good luck in your explorations.
