> In that case, looking unique and standing out is a benefit.
In case of a store, having say, a share button that matches the Android standard for it, rather than the Apple version, makes more sense to Android users. It makes your site easier to learn which is a benefit.
I am not saying all pages should be 100% "CanvasText" on "Canvas," and use the browser default font. There's so much room for customization that can be done. Splashes of color. One or two judiciously-chosen fonts that aren't jarring. However, the fact that we have at least 100,000 separate implementations of a 'dropdown/popup menu,' is not worth the downsides. Each of these custom controls has its unique bugs and accessibility flaws and they usually are inferior in many ways to the real UI elements that have been tuned for literal decades to work in all scenarios for all types of users.
