Differences in SQ between EL34, KT-88 & 6550 Tubes

I'm continuing my tube education and am considering buying a tube amp. Is there a distinctive difference in SQ between the EL34, KT-88 & 6550 tubes? Is there a pecking order as your climb the tube ladder for SQ. I am aware that different brands/versions of either tube can sound better than the other. But I was wonderful if one tube type is generally better or has a distinctly different sound than they other.

I would differ to Albert since he's sp[ent much more time intrenches but I had thought that the KT88 provided more in the bass region and had more dynamic slam.6550 has econonomy going for it and EL34 was the best for midrange perfecty for coherent two way monitors where the midrange is the thing to be accentuated with it's warmth and timbre.But again amp makes big difference.New mac amps use the KT88 to full advantage and are designed to do so though again the roll is most expensive of the 3.
