Moissanite engagement ring — has anyone chosen one over a diamond?

My granddaughter is engaged and we have been talking about rings together. She loves the look of a classic solitaire but is also keen on something ethically made and not wildly expensive. Moissanite keeps coming up — it looks very like a diamond and is supposed to be very hard-wearing. I have been looking at moissanite engagement rings at moissly.com/ to get a sense of styles and prices. Has anyone here (or your family) chosen moissanite for an engagement ring? How has it held up over time, and did you find it easy to keep clean and sparkly? Any advice on settings or what to look for would be very welcome. Thank you!
