no real advantage, but here is my take : cloning is like using a copy machine. take a copy of the original, all is OK. but keep making copies of copies (Seed Original Mom->clone->clone->clone->clone ... etc) leads to genetic drift (how does copy # 20 look? missing ink/spaces, looking distorted.) and lower long term yield/potency (I've even had a couple strains loose smell completely).
so for me, I use the original seed mom until she has problems in her 18gal container (I up-size pots every couple months to avoid rootball/container size problems), then she gets culled and replaced by a 1st generation clone from her. I never go deeper then a 3rd gen clone mom).
a seed mom is usually more vigorous in her growth then subsequent clone moms (same as hybrid vigor)
