Sadly just a lot less overall clarity. Less coherent sentences making substantially less coherent points. People made fun of him eight years ago for this but mostly if you paid attention to politics and the goings-on you knew what he was referencing and he was making coherent arguments (whether you agreed or not). These days it’s much less follow-able.

I can see that, though he might have also just widened his scope a bit to personally less familiar topics during the second run, eg. BTC. The talking points during first run and term seemed pretty narrowly defined.
