Well, I will avoid the Oakhurst route primarily because I've been on it a dozen times. I like roads and routes I've never traveled. I don't really care if it takes longer to travel the shorter distance, I will personally enjoy it more.
In fact, there was something somewhere about the 140 being one-way stopped because of some rockslide, or was it some weird crossing of the river? ... anyway, even with delays, I'd rather travel the road less traveled ... by me. Not saying anyone else should do anything in particular. But there's just no denying that one entrance to Yosemite is from the north, one from the west, and one from the south. It seems pretty logical which one would be last on the list for somebody coming fromt the north ... but my advice is no more or less valuable than anyone's. Indeed the SIL who lives in Oakhurst seems a more than reliable source (but, hmmmm, of course she's recommending you travel through Oakhurst).
I really enjoyed Nirvanaman's more direct route vis-a-vis Kings Canyon. It may have taken longer, but it was a shorter distance and far more beautiful. Them's my priorities.
Your mileage may vary ... and that phrase is both literal and figurative in this case.
