From my experiences with various TOTL arrangers, the Tyros 5 easily commands the top position for my needs, even despite it being 3 years old.
For my one do-all keyboard arranger, the Tyros 5 easily provides the best realistic guitars in an arranger. All the tools for my arranging, composing, recording, and live performance are nicely realized with the Tyros 5, including guitar voices, guitar DSPs, and all the strumming and arps.
For me, Yamaha styles rule. I tried the Audya. Some nice realistic drums and guitars, but too limiting in the creative process, plus other lesser quality voice parts in the mix really degrade the realism.
Programming or editing your own guitar parts with strumming effects are easily found on the Tyros 5 arranger with plenty of multipad effects and well programmed guitar parts in styles, which are fully editable verses limited audio guitar loops found in other arrangers.
I love Audio Styles with audio drum parts (and certainly audio guitar parts) because the feel and energy can be felt from the live musician. With the debate of Audio Styles verses regular midi styles, give me both, but certainly the voices, drum kits, and programming can constantly improve to increase the realism. Can't wait what Yamaha produces for the new Tyros 5 replacement.
For me the Kronos/Oasys guitar strumming was really good, but I have perhaps even better strumming realism and guitar voices in my Tyros 5 without having to add another keyboard.
There are dozens of Tyros 5 multipads that can follow your chording with realistic strumming and arp patterns with or without a style playing, plus the guitar can be changed in Multipad Creator or modified further. There are hundreds of other downloadable Yamaha multipads available, saying nothing of thousands of Yamaha styles and styles with well programmed strumming.
Here are few of Yamaha's Guitar Multipads.

Here is a simple recording recorded via MIDI from my OMGuitar app to my Tyros 5 using the S.Art Steel Acoustic guitar voice. See photo for screenshot.
