Hi Ttidus
It’s all down to which you personally like the sound and feel of, which is a decision only you can make.
However do a search on the Synthzone board for G70 and PA1x and you will find quite a few discussions that might help.
Also have a read of my personal review of the Caister 2005 Organ and Keyboard Festival, which includes these instruments along with others.
Hope this helps.
