#1 gets my vote.
IMO it benefits from De-essing, (the ess sounds are a bit too strong),
and cutting the bass increases intelligibility, (as the air-con is bassy), at the expense of fidelity/gravitas.
There is a free Audacity de-esser plugin: desibilator (not real-time).
ToneBoosters have 2 free 64-bit de-esser plugins, (real-time): the simpler-looking one is sufficient.
