TPS without use cases and idea is useless metric. Im not sure that it can tell you anything about the project
True and these gimmicky TPS are only at peak testing and by increasing TPS as much as a blockchain can it means they are sacrificing something whether from security or anything else not to mention most of the coins who advertising such high TPS will never use a quarter of that capability, high TPS without overflowing traffic means it's no use since lets be real, who cares if a blockchain has 10 million TPS capability but no one uses it.
