Greenfield rear kickstand is what I use, on everything but my disc brake bike (doesn't fit) or the vintage ones with built in stands.
If you want one, get one. Don't let people shame you into not using one, it is one of those topics that the "purists" can't resist telling you how wrong you are for not doing it their way. Contrary to what they will have you believe, bikes fall over propped against stuff just as much as they fall over on a properly installed and adjusted kickstand for me, which is relatively infrequently in both cases.
