What’s your favorite ECC 85/6AQ8 Tube?

Hi I am hoping to get some recommendations for this tube as well as a reliable source to purchase. Thank you in advance. 
I tried a pile of 6AQ8's in my EAR 890 amp, and I liked the Amperex best, but I have at least 6 different varieties.  I know longer own the amp, so I really should sell off some tubes.....   (Got a bunch of 12AX7's, Ei KT-90's, and others.  I should get organized and sell some this winter.)
