Hey, Glenn - How's it goin'? As you observed, each of the recommended kits has something to offer. Here's my take. The Vector will be the best-performing plane. It'll also require more work, although not much more effort than an Oriental
kit.
The Twister (Fancherized, or not) will be a quick-build plane and a very good Intermediate ship. It'll be inexpensive to build and fly. Won't perform as well as a good Vector (but, then, few will).
I would rank the ARF Oriental last of the three for only one reason. I'm so darn tired of saying (or thinking), "Rats! Why the @#$% didn't they spend 25¢ more on this widget, and do it right? Now I've gotta spend 50¢ for a good widget, an hours replacing the widget, and two more hours repairing the area where I replaced the widget"! This "widget" usually refers to replacing leadouts, replacing clevises with Rocket City Ball Links, a poor/weak bellcrank, or preventing the covering from stripping in flight!

But honestly, once fixed up, the ARF Oriental is a wonderful flier, and not every one of my examples of "widget" apply to this plane! I'd just get the Oriental kit and build the whole thing.
