The difference is, that those both have about same level of output with F3.5 as that DA*60-250/4 starts to have around F5.6+. And that means considerable amount of light. And if you are shooting portraits and you dont care about borders, then even F2.8 is ok.

Hi-ISO means that dynamic range says bye bye and noise rushes in. Especialy in weak light conditions.

And sure F1.4 lens is even better.
