A lot of us don't like blank modifier keys, unless the entire keycap set is blank.
I do use the "standard"/"common" layout as seen in many ergo keycap drops here on Massdrop, aside from the thumb cluster; it's pretty much the default layout for the Ergodox Infinity (see the photo of my Ergodox Infinity with Jukebox SA).
That said, because these keycaps are DSA (uniform profile), and there are variations of several of the modifier keys in the set, you can do a large variety of layout options with these.
I bought this exact set from KBDFans, and it's not bad. I wish it had a 1.5U `~ key instead of esc (since I use ``` all the time for markdown), but it had almost a perfect layout for me. I still use a 2U XDA convex for spaces, since there is no convex DSA 2U anywhere.
