Lycoming Or Superior Replacement Valve Springs

[RBosque]

The valve springs in my Lycoming I-O360 C1C6 have some corrosion on them and my IA recommends replacing them. I see that the springs are available from Lycoming and Superior Air Parts. The ones from Superior are less expensive. Is there a difference in quality? Are the Lycoming springs better than the ones from Superior? (The Superior springs are almost half the price of the Lycoming ones.)
