You need some technical specs on the website. How many DOF does it have? Does it have joint angle sensing? If so, what's the resolution? What's the interface to the servos? What's the payload capacity? Does it have integrated motor controllers? How long is it, and what does the dexterous workspace look like?
As a roboticist, what I'd vote for, in order, is:
- more degrees of freedom
- interchangeable tools, either an actual tool changer (unlikely at the price point) or a fixed bolt pattern with electronic passthroughs
- better joint sensing, e.g. absolute encoders, joint torque sensing
- fingertip force sensing
