EL 34 vs. KT 88 ---- What's the difference?

How about "more to my liking." Better looking? Easier to dust...repels stains...dishwasher safe...A Good Housekeeping seal of approval...burns your fingers slightly less when touched (actually true with KT77s)...preserves the smell of the original recording space...can be used as money in Easter Europe...dry cleanable...slightly slows down fast parts and speeds up slow parts...quiet when not in use...

Lance-Baker1, You sound knowlegable. Lead they way. Give us the words.

Sorry. If I said wrongly.  Weather EL 34 or KT 88 tube. First they have to depend on your input tube. The smaller tube , will control the input sound. Power tube will only gives more power to sound. Same as throde , they gaves louder bass.
