Which line to use for water feed?

I am installing a new sink and toilet. Should I use the steel braided lines for the water feeds or do you recomend something else? I noticed at Lowes that the steel braided lines are made by Watts which makes the Floodsafe lines that have bad fittings. Should I trust their steel braided lines?

They will be just fine.

The problems are with the FloodSafe device, not the connections.
