I have both, and they're pretty much built the same way.
No reason to get rid of either, or build them all that differently. Both thrive when fed the same ingredients: 160mm fork and solid parts. The fact that one is a hardtail makes them different enough.
If I had to chose one it would be the fully, and if for some reason I had no bicycles tomorrow I would buy another Covert first (and I would in fact buy another). Full suspension covers a lot of ills on those really rides when you'd otherwise be off the back or over the bars. I like my Covert because I know I can ride it anywhere.
