I’m about to install engineered walnut in a wood-frame apartment building. There is a unit below. The floor will be nailed with U-shaped staples every 6 to 8 inches.
Is there any advantage to using sound muffler underlay? The extra cost would be about $300, which I’m happy to pay if it makes a difference — I just don’t want to shell out the money and later find it was a total waste of time and money. There is no condo or bylaw requirement to use underlay.
Thanks for any and all responses.

It will reduce sound, ambient and impact but to what degree depends on a lot of factors. There are different products and each job site may be unique. On a nailed down floor, the best will be reduced due to the direct attachment to the subfloor. By and large, the sound reduction is not a lot but it is something. You won't have another chance until the floor comes up.
Beat it to fit / Paint it to match
i'd use 30lb felt ... with the mechanical attachment... i don't think you'll gain anything over use'n 30lb fellt... if you were to float it... maybe... just maybe it might be worth it... i'd keep my $300
