Less algae is better for plant tanks. UG filters are not what folks
want for the plants either.

Besides plants roots getting tangled in the UGF, why are UGFs negative
for plant growth?

If you were to use fertilizer sticks in the gravel near the roots, a UGF
would pull the fertilizer's compounds into the water column, probably
causing an algae bloom. Layering substrates is also made more difficult
with a UGF.
