Alternative to Autodesk Sketchbook Designer ?

Hi to all and really thank you for your time to suggest Clip Studio. Really looks pretty similar to SB 2012, although its UI is a bit more complex. Perhaps though CS is more powerful.
On SmithMicro’s website is see 2 version, the CS EX ($209) and the CS Pain PRO ($47.99). Does the CS Pain PRO have the vector sketch ability? Like is see on this video :

This one should be the EX version but i wonder if similar functions can be performed in PRO as well.

Thanks a lot!
