There is sub 100ms input lag in good conditions with cloud gaming, and it goes as low as 60, and it will be better as more servers come online as everything from gets optimized for latency. Is it worse than PC with same games? Yes. Is it worse than game consoles? Not really. But it removes whole sets of "who shot first" problems, and if we are talking about actual latency for your decision to take effect(input lag+network lag) cloud might just be better in many scenarios.
