It took me probably a day of testing to convince myself because I really didn't find a simple example. I have simple atomic classes that create a set of columns I use frequently that solve problems that just a few years ago were always an annoying mess.

Grid requires no/fewer wrapping elements, solid outcomes (ie, code matches result more often than other layout methods from the start) and lots of minor properties for edge use cases. And this is just a summary of the benefits.
