I personally like the Skywarp Horizon, and it seems like it would be more economical than the other two models for sale. I can literally imagine a whole area of some theme park with all three models
While it might be the cheapest to build, I think eclipse is the easiest to manage and might be cheaper to operate. Eclipse is the only model with a single platform with only one entrance and exit. Everything else will have two separate stations, and two lines, or a split.
