Whorly Rotala is the tidier fit when space is limited.
Whorly Rotala fits a routine built around high light and required added CO2, with fast growth, high maintenance, and advanced difficulty.
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.
Carolina Fanwort is rooted in substrate with inert substrate is fine and feeds mainly as a mixed feeder. Whorly Rotala is rooted in substrate with nutrient-rich substrate preferred and feeds mainly as a mixed feeder.
Their mature height diverges enough that they stop being true one-for-one replacements.
If the tank already has several demanding plants, the easier choice is the one that matches your existing light, CO2, and trimming routine.
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.
