By going OTL the amp is instantly wider bandwidth: deeper bass and more extended highs. Its also instantly more transparent. This is easy to demonstrate regardless of the competition.
The flip side is you have to be more careful about the loudspeaker. But in practice, that is true of any amplifier.
Generally speaking, you want a speaker that is at least 8 ohms in the bass or better yet 16 ohms, unless you have one of the really big high power OTLs, for which 4 ohms is not so challenging.
Another aspect is that OTLs often have more power tubes. But heat does not seem to be a problem because of that. Some OTLs run cool and others do not, depending on the class of operation and the power tubes used.
