Both skis are totally different,
Thall is very soft and has butter zones, It is very park oreintated so if u want some all mountain versitility go the Pipe cleaner. Having never ridden the Thall i can say much more than it was built for 1 thing which is park and urban. Prb even to soft to go off big tables.
Pipe cleaner is fuckin fast pipe ski but is also very versitile. Its stiff for the pipe so it can tackle groomers as well. THe softer race base is better to keep off rails but the odd rail here and there shudnt do to much. THe base is also high mantenence.
A little more info would be good like what do u want to ski, where do u ski etc. weight, ability level and height.
