I have an issue with the lighting, I prefer lighting that is similar or the same as Sunset Valley. I found Midnight Hollow to be too dark, and I think maybe Aurora Skies is a bit darkish too. Lucky Palms has this different color/light that tends to be orange if I remember correctly. Monte Vista too. I guess it can fit when you want some medievel vibe.
From this aspect, Barnacle Bay and Hidden Springs were the most convienet for me to play (meaning the most natural lighting as I prefer...)
The CC is also a consideration, I like Aurora Skies' CC the most.
