Ooh, just found this thread. I'm in the middle of completing an aromatherapy masters apprenticeship, so I'm very into essential oils right now.
IMO, the first link you listed, Florihana, has the world's best essential oils. They are like works of art, and bursting with life and energy. I love ordering from them and don't think you can do better. Plus, the man who runs it, Alain, is very nice.
I have it on good authority that Fragrant Earth
in the UK also sells amazing oils. But I haven't ordered from them myself (yet). Am told that it can be a bit of a hassle to get stuff to you (due to the international customs stuff) but again I haven't tried. The stuff from Florihana (in France) gets to me super fast.
On the US side, Original Swiss Aromatics
is terrific. That's Kurt Schnaubelt's company, and he's a leading authority on the scientific properties of EOs.
Hope this helps (even though it's over a year since you asked).
