Hey kingfish,
Good question. Presently, I would say I like seed's much better. How can I make this short and sweet? With seeds I think you're always offered fresh new genetics. The strain quality is unsurpassed, provided you buy from a reputable seedbank. I have only ever had one problem with seeds. I had ordered 3 different strains, same breeder, from the seedbank I usually get my bean's from. Two were Indica dominant and one was a Sativa dominant. I cultivated the one I thought was an Indica dominant but I soon discovered in regards to the leaf shape that this was the Haze I had purchased. The bags were labled wrong. Other than that, they're relatively cheap, thousands to choose from, I've personally found even some of the cheaper seed's made beautiful, high yielding plants. I have no use for a mother plant, only one at a time for me. Also, I cultivate a lot of Auto's, so always by seed. They arrive in the mail, and there's no bugs attached. I've got a lot of houseplants, an infestation would be a disaster. Starting from seed let's you achieve a very uniform plant, structurally and genetically, trait's that Breeder's stride for.
Anyhow, that's my two cents. Everyone kinda does their own thing. To each their own. So it's definitely seed's for me.
Peace,
