In all honesty, HTV's work is more faithful to the original effect. CBS-D looks better (and obviously I prefer it), but you can understand why HTV's effect looks the way it does.
This is how I feel.
Faithful to a fault. Faithful to the point of some shots looking like they were upscaled....or using very low res graphic elements.
CBS restored the show in a way that looks how I ahem "remember" it in my mind, but HTV went in the complete opposite direction and made sure we were aware of just how the show really looked.
I prefer CBS-D's approach.
