It’s always good to keep busy.

Yamaha Arrangers still use AWM1 (Like the Electones) only the Workstations use AWM2.
The main articulations on the SA2 voices relate to the attack and decay phases (There are also other effects that are incorporated, but not directly unique to SA2) whereas SA1 concentrated on the Attack phase. (This is the reason you only have 2 Art buttons)

The Korg DNC has 3 articulation controls and is much more flexible than the T5 Art buttons. (The SA/SA2 has the advantage that everything is programmed into the voices, (Something I hate on a keyboard as it takes much longer to edit) whereas the DNC effects allow you to do more your own thing, (My preference) and it is purely personal choice as to which you prefer)

Although the Korg is a little heavier, it is more substantially built than the Yamaha which depending on its use may make a difference. (As arrangers are designed for the home hobby market super strong is of little relevance due to the fact that home players usually upgrade almost as much as they change their socks, compared to pro users who tend to keep their equipment for centuries)

The T5 ensemble section is good, however apart from the Classic and theatre organ, the rest of organ world is limited, having little in common with the instruments that they are supposed to emulate. (If you particularly want Hammond emulation then the Korg wins hands down)

In the end though, there is more to an arranger than just sounds and features, and the only way to see which suits you is to actually play them live.

Hopefully the above will give you something else to ponder over.

Korg has way more assignable sliders and knobs.
The vocal harmonizer is miles better than Yamaha.
The drum kits, with the exception of audio ones, are much more realistic.
I find the gimmicks on many of the Yamaha guitar sounds put stuff in at the wrong times. I prefer to do it myself.
Korg has the EC5 multi foot control which is light in weight, inexpensive and totally programmable. Yamaha's only option is the very expensive, very heavy, MFC10. The Tyros does have 3 programmable foot pedals, but the PSRs only 2.
I of course have not played a PA4X, but the 3X, although similar in weight to Tyros, is a much more manageable size, and is far easier to lift off the stand, put in bag and transport.
I would not use the organ world and ensemble sections, although I can see where many might. I want to sound like a small combo, not an orchestra or movie score, or most of all a big organ.
There are positives on each side I'm sure we're overlooking, but at least for me it's an easy choice. And isn't it wonderful we have so many great choices!!

So Don you like Tyros 5...lol

Sure I like it. Not enough to buy it instead of either Korg or Ketron though. I notice you don't have one either. Is it because of the size and weight by chance?

Bill there is no AWM1 or 2 anymore, there just is AWM, an ever growing synthesis engine, T5 is state of the art, Motifs engine is comparable to T3. Tyros has grown further..( tough Motif is much more editable)

yamaha is comtinously advancing the AWM engine, they keep adding more and more virtuall stuff to it. AEM, EAM, SCM, RDM, VAM, AFM,.. All are types of virtualisation added to the The AWM synthesis engine tahts kind of modular, so every instrument gets the things it requires, SCM and RDM for pianos, and VAM and AFM for upcomming synths.. Combining samples and virtuall synthesis engines..
