I don’t have an answer to contribute, but I would be very interested in
hearing about experiences in terms of their relative runtime
performance.

My gut feeling is that an an indirect function call for every (>>=),
with many calls to `lift` each time, would make a deep monad
transformer stack much more expensive. A free monad approach seems to
be more sensible to me. But maybe GHC is doing a better job optimizing
this than I would think?

So if you have any number-supported evidence about this, possibly from
a real-world application where you tried to use one or the other,
please share it with us!

Thanks,
Joachim
