I alternate, but overall I feel lrs is better for larger fish, some of my smaller fish don’t take it well (even lrs nano) and Rods also has smaller items, like golden pearls, included for coral feeding.
Both are top notch and I have been buying lrs more for the bigger chunks for nem feeding, but I feel Rods targets more organisms.
Edit looks like rods no longer has golden pearls but baby brine which is probably better.
