TSAC @ 8 kbps is comparable to Opus @ 24 kbps, maybe a bit more too. Great, I'll give you that. But that's it. TSAC has the same limitation as all other AI-based audiocodecs. It doesn't scale up with higher bitrate.  Nothing remotely close even to the modest HE-AAC@48 kbps, leave alone any higher bitrates/transparency levels.



Comparable how? I'd say TSAC @<any bitrate> is not comparable to <non-AI codec>@<any bitrate>. They are just too different for one to make such comparisons.

TSAC, especially at high bitrates, is very impressive actually. Better than any other codec I came across. Too bad it's not usable in practice, or even open-source (allowing experimentation, alternative models, ..etc).
