Spiral flute vs. O flute bits

I’ve been using up and down cut spiral end mills.

The down cut bits pack chips into my profile cut. A pita to clean out and I know that can’t be good for the bit.

The uncut bits frequently leave rough bottoms and usually fuzzy at the perimeter.

I’ve been doing a little reading about O flute bits. Can anyone dumb it down for me?

Will O flutes help with deep profile cuts?

Will they help give me smooth pocket cuts while efficiently removing chips?
