Fuji XF 23mm f2 WR - The little lens that does it all … but can I justify it’s newer bigger brother?

I’ve used the Fuji XF 23mm f2 WR lens for the last three years and it’s become my most used lens. With the new XF 23mm F1.4 LM WR finally about to start shipping, it’s time for a review and reflection on it while I decide whether an upgrade is worth it for me.
