Honestly, I haven't personally tried Fujidenzo kasi we went with LG, but a few of my mum friends have the 20cf side-by-side and they're really happy with it, durable, good cooling, at hindi sobrang mahal compared sa other brands. The 15cf multi-door sounds practical para sa smaller kitchens, pero since walang personal experience ko dito, baka better pa rin mag-visit sa appliance stores to compare in person and check the warranty kasi that's usually the deciding factor namin pagpili ng ref!
