Hi John C

No one else can answer that but you, as it’s a very personal thing.

My favourite is the PA4x 76, as it sounds more real and lifelike, plus it has very good editing facilities and a Touch Screen, whereas the T5 I find OK, but apart from a few features (General voices, Ensemble, Part of Organ World and SA (NOT SA2) voices) I find it lacking compared to the live performances I regularly attend. (If I was going for a Yamaha I would choose the PSR 970 or a used T4)

In the future also think about adding a pedal board (Go for at least 17) and a 2nd manual (There are plenty of dedicated kits out there) so that you can really do your own thing.

Hope this helps

Bill
