Elite cuttings give you a known quantity, which seed never does, but you inherit whatever pests or viroids came with the cut. Starting from regular seed is slower and messier, though the plants arrive clean and you own the selection rather than borrowing it. Arguments on both sides, including the hop latent viroid problem, are summarised on https://breederregularseeds.com. I lean toward seed now, mostly because tracking down a healthy cut has become tedious.
