Welcome to Cloudy Nights!
Both are quite capable. The pricey one, of course, is very good.
Samsung SCB-2000 is a very good starter, this will buy you time to learn more, before you move to a high-end.

Which specific cameras are you comparing? Both vendors produce a variety of cameras at a variety of price points.
What is the consensus of users of these cameras? Are they similar in performance on DS and SS objects or dos one outstrip the other?
GStar and Mallincam video cameras are similar in concept, in that they are both video and not single shot CCD based. Beyond that the execution of them is somewhat different (despite the fact that they look similar). The Mallincam video cameras are produced specifically for astronomy (low noise circuitry, and most models also have onboard cooling and much longer exposure capabilities). The Gstars are based on industrial video cameras selected for their appropriateness for low light deep space viewing. When they have the same sensors at shorter exposures (4-5s) the Gstars and Mallincam video cameras will produce similar deep space and solar system images. Neither are optimized for solar system viewing but certainly do a credible job.
Where most of the Mallincam video cameras excel is in longer exposures on deep space objects. They are most often used in the 10-45 second range but are capable of going much longer, in some cases to many many minutes (exact times depend on the model and whether a PC is being used for control).
In general a Mallincam Jr. is similar to the Gstar color cameras (both are x256 or 4-5s uncooled cameras). Monochrome Gstars (also x256 exposures) produce some stunning images but remember most of the images you see posted are the result of lots of work and time, using color filters (lots of exposures) and lots of image stacking. When you're comparing images online pay close attention to whether they are single shots, single shots with post processing, or stacked shots with post processing.
