Which one should you choose?

The Mastiff is famously low-key for its size, a couch-companion disposition despite its enormous frame, while the Akita runs a bit more active and alert day to day. Grooming favors the Mastiff clearly, its coat-care needs close to nil against the Akita's thicker, seasonal-shedding coat. Family fit tilts Mastiff too, generally described as a patient, gentle giant around its own household, though its sheer size still demands careful supervision around small children regardless of temperament. The tradeoff concentrates in cost and time together: a giant dog eats and costs more, and the Mastiff's typical years with its family run shorter than the Akita's. Someone wanting the calmest possible giant-breed companion and prepared for higher feeding costs should choose the Mastiff; someone wanting more years together, lower costs, and a slightly more active, independent dog fits better with the Akita.
