When you say "studio light" kit do you mean for use inside exclusively, combination of in studio and on-location. Working alone or with a crew? What type of shooting?
These are all factors. Some advantages the Einstein offers; modeling lights, quick recycle time on mains power, comprehensive remote control capabilities with Cyber Commander, large selection of modifiers.
The Cheetah Lights (180/360) are relatively small, easy to setup and use with battery packs. Can be used with most S mount modifiers with the Cheetah Pro Brackets. There are two and its best to have both depending on the size and weight of the modifier.
The CL-600, in my view, based on specs is a little closer to a studio strobe but still more for location shooting than studio shooting.
One consideration is flash duration. The Einstein, as well as the CL-180/360 use an IGBT power control circuit. This control means that as power is reduced the flash duration gets shorter. Most studio strobes, including the CL-600 use a voltage based power control circuit. This control method means that as power is reduced the flash duration gets longer. If you need or want to stop action with the strobe this is a hindrance.
