By 'best' you mean in some kind of objective way, like 'very polished' and 'lots of juicy exclusive content' the likes of which we don´t see in other Switch 3rd party games?...or more like in a subjective manner?..because for someone who doesn´t care about JRPGs/Dragon Quest then it doesn´t matter

If it´s the former I guess it might just be the best indeed.
