Side-by-Side Comparison
The better choice is usually the plant that fits your existing light, space, and maintenance routine with the fewest compromises.

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.
Matto Grosso Milfoil is rooted in substrate with inert substrate is fine and feeds mainly as a water column feeder. Pearl Weed 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.
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.
