Everything is a trade-off, no? Flooded cell NiFe have a fairly high internal resistance and, as you note, a large voltage swing. But they are the champs when it comes to longevity. I had one 12V NiFe battery that I used for ham radio that must have had several thousand cycles on it, and was still in good shape when I sold it at a hambest for more than I paid for it, some ten years later.
