I never had a WP, but I do have a few Zunes. The Live Tile main screen for WP is a bit too busy for me, but I would love to have the slightly cut-off styles in settings and menus that it and the Zune models had. Just really vibed with the look for some reason.
Windows phones were really solid, OS was very user friendly and stable. I personally didn’t feel the “app gap” that a lot of others complained about but, I use my phone for browsing, calls & text. If I recall correctly it was also ahead of the curve with PWAs, integrated them really well. And price/performance was good on some models like the Lumia 650.
