I've used bread yeast, Lalvin D47, Lalvin 71B-1122, Lalvin K1V-1116, and Lalvin EC-1118.
Depending on what mead I'm brewing, I think I like D47 the best. Of course, Joe's Ancient Orange works best on bread yeast. Just plain old Fleishmans is what I use, but I make sure to avoid rapid rise, or bread machine yeast. Just the regular is what works best for that. I've also tried it with wine yeasts, and the wine yeasts made me have to age it out much longer. Rapid rise yeasts, I think will not take the alcohol levels very high, but plain fleishmans will take that mead to about 12-14% ABV.
I personally haven't used liquid mead yeast, but I did try a yeast done with the sweet mead yeast, and it was very nice! It kept all the floral notes of the honey. It was actually almost too perfumey. But for the meads that I usually do, D47 with yeast nutrients split up in 3 batches provides great results.
