How does this compare to ABC5401 (Lowes item #462450)?

The Frisco, model CB9521, is a value grade. This indicates that there will be more natural distinctions in the wood; knots, color variation, etc. You should expect the standard 5-10% waste; as with model ABC5401. The main difference between these floors, is the warranties; the 15 year and 50 year respectively. I hope this information is helpful.
