Right next to it on the list
A rank or two either side of the Vissani HVUF11SL: Perlick URS15T*1-5-**** ($47/yr, 249 kWh/yr), then Vissani HVUF11SLF ($47/yr, 249 kWh/yr).
Comparing Vissani's own models

Cost over its typical lifespan
NAHB's Study of Life Expectancy of Home Components puts a typical refrigerator's service life at 13 years; run the Vissani HVUF11SL that long and it costs about $609 in electricity, on top of whatever it cost to buy.
Is it worth replacing?
Efficient as certified refrigerators go, $47/year is a reasonable baseline if you're comparing what else is on the market.
Worth comparing a few current certified models before deciding.
If you're keeping it
A refrigerator like the Vissani HVUF11SL is a real household expense whether or not it needs replacing yet; a protection plan is one way to budget for a repair rather than a full replacement.
