Pleated vs. flat-front pants ... is one out of style?

There's a brand/style of microfiber golf pants I enjoy wearing -- and to this point, I have two pairs of them with flat fronts.

While I am a bigger guy, I have never needed pleated fronts for comfort, and generally, I like the style of flat front.

However, there is a huge 50% off sale on the pleated front version of these pants in a color I do not have -- and I was thinking about grabbing a pair because of that.

(1) Are pleated-front pants out of style?

(2) Given I generally wear my button-down shirts untucked anyway, will it even matter much?

Thanks.
