Differences in tube sounds: 6550 / EL34

I would like opinions on amps that use these two types of tubes. In general, what charateristics do these tubes possess?

When i owned the tube gear I prefered the Ei Kt-90's over either Kt-88, 6550 or El34. Mostly out of reliability issues. Some amps built exlusively around El34 tubes could sound wonderful. Like the older CJ amps.
