Prior to liner should I use the foam 5" floor coving?

[dw9000]

I am debating on using floor / wall coving. Looks easy to install. Is there a big benefit to not having a 90' angle between the floor and wall? Will it be a lot easier to keep clean? Easy on the feet while you are in the pool?
Any substantial benefit?

This is the kinds of stuff:

I would not have an above ground pool without it! It helps with cleaning (no sharp edges to try to keep or get clean. It keeps the liner from going out under the wall.

All good and no bad here for a cove!
