My Sigma SD1M still produces mind-blowing images I can't do with high-end Nikons and Canons. Foveon can truly make magical images, though there were so many issues with DSLRs it shipped on, e.g. they were almost always awfully slow and had very bad (but film-like) low-light performance. Also, original research suggested that to get realistic colors, up to 7 layers are needed. Bayers OTOH just interpolate and cook colors, but with the increase of resolution might at some point perform similarly, when lens limit is hit. Foveon was also always manufactured by a far worse process than e.g. Sony top-end sensors, and its quantum efficiency was orders of magnitude worse.
