If "best" means absolute maximum lifting capacity in a single airframe —then yes, the is the best cargo aircraft ever conceived. It is the aviation equivalent of a blue whale: slow, inefficient, beautiful, and impossibly large.
While it does not exist in reality, the An-990 is celebrated in simulation for its "gargantuan" proportions and theoretical "Graphene" construction, which allows it to reach weights and payloads impossible for current real-world materials. antonov an990 best

Despite its "best-in-class" potential, the An-990 faced insurmountable hurdles that kept it grounded: Its massive wingspan measures 870 feet (265
: Its theoretical wingspan of 870 feet (265.2 meters) is three times larger than that of the legendary Antonov An-225 Mriya , the largest real aircraft ever built.
Could you clarify whether you mean:
Very few runways in the world could support the weight of a fully loaded An-990. The cost of upgrading global airport infrastructure to accommodate such a giant was prohibitive.
