I've written a review and comparison of every switch I've tried, and whites are my favorite cherry MX switch. I didn't notice any inconsistency when I did my initial review, but since then it's all I hear about with whites. It's all opinion, at the end of the day, still. My board, however, wasn't NEARLY as inconsistent as the one you showed. When you start carefully pressing switches one by one to test them, you can definitely tell that some are louder than the others. However, none were ever anywhere near as loud as greens or as quite as clears. When I'm typing, I honestly can't really feel any inconsistencies. It's only when I look for them that I find them.
The board I used for my whites was a ducky yellow edition, with the one used for greens being a g2 pro. Basically the same keyboards, other than color, backlighting, and pbt dyesub vs. engraved pbt caps. It's got to be batch to batch consistency that determines what you get. I don't know if you got a lemon and most whites are like mine or if I just happened to get a remarkably good one and most are like yours.
Either way, I'll update my review to reflect that I may have gotten a special batch.
