Care and Scape Differences
Role overlap lands at 82/100 and care similarity lands at 76/100. Treat those numbers as a shortcut for the decision, not as a replacement for looking at mature size and placement.
Cardinal Plant is rooted in substrate with nutrient-rich substrate preferred and feeds mainly as a mixed feeder. Parrot's Feather is rooted in substrate with inert substrate is fine and feeds mainly as a mixed feeder.
Their mature height diverges enough that they stop being true one-for-one replacements.
Also watch that one of them casts noticeably more shade, so the effect on the tank feels different.
Practical Recommendation
If both are available, pick based on the role you need most: the tidier mature footprint, the better cover value, or the plant that matches your current routine without upgrades.
A practical way to decide is to imagine the tank six months from now. The better plant is the one that still fits the same space after several trims, not the one that only looks right on planting day.
