By using a FRFR speaker, and dialing in your tone with it, it provides a world of versatility in that the tone you monitor with is the tone that your recording (which is as simple as plugging in a USB cable with the Axe), whereas with a cab, you need to mic it, it might be an issue of how loud you can record/when you want to record depending on your living situation etc.
Likewise, for gigs you can plug just straight into the soundboard and even use the house monitors (assuming they have them), which makes traveling for gigs far, far easier than having to lug your Axe, your guitars, your cabinet, your power amp etc. If you don't have a car, I'd try to be as mobile as I could be
Heck, I might consider an AX8
