Cuttings will always do better in a potting mix rather than a water solution as they take up vital nutrients instantly rather than being in low nutrient water. I have noticed that water propagation is very popular within the houseplant community, I believe this is due to its simplicity and it seems somewhat less intimidating than cuttings within compost etc. I have a seen a couple of videos on youtube showing how to take houseplant cuttings, some techniques were very interesting! I have seen some leaf cuttings too on youtube, Plantingmemories has some nice vidoes on this, worth a watch. he has Philodendron micans but im not sure if he has done a propagation video of that
