If you want easy play (Press a button and everything is done for you) then the T5 is the one to go for, however if you want to make the instrument your own, (IE: Not sound the same as everybody else that has a T5) then the Korg is way ahead in most departments.

If you want the best however, then get a T5 and a PA4x (Use a dual keyboard stand) and also add in a Roland Integra module, then you will really be in heaven, with the only way forward after that would be getting a laptop and some VST’s. (This really would take you to a whole new level)

The only way to see which is best for you is to try out both keyboards, then go with what your gut tells you and enjoy.

If I was forced to have one arranger, then for me personally the PA4x is a no brainer, however it may not suit others.
