To the OP:
I can understand your frustration. It's not a top quality soundcard.
I use the Axe as a standalone to record guitars and basses for production projects. It works fine, has never hampered my workflow (I may be alone in this), and has become a one box solution for location guitar reamping/recording. I am prepared to suffer small issues as a result, as I remember cutting tape, DIing to reamp, and all of the other workflow hindrances of old. The Axe has been a one stop cost effective tool that has done away with my amp buying and hiring costs, and has actually resulted in my work being turned in quicker and with a lower budget than would have been possible without.
I currently use a Liquid Saffire 56 and Octo Pre Mk2 for interfaces. They're superior as interfaces go, but their guitar modelling is non existent.
They're handy for drum recordings, location work and orchestral, though!
When a piece of equipment is specialised to a specific job, other considerations are secondary. We do not currently have a USB Neumann U47 mic, for instance, nor an effective all round guitar that digitally interfaces with a computer via USB. Gibson have tried new technology with their 'Robot' series, and we all know where that led us.
In short, we cannot expect a USB guitar to compete with an Apogee interface. We cannot expect the worlds premier amp modeller to compete with an Apogee either.
I would rather have the Axe with USB interfacing (and dare I say it without opening a can of worms.... AE3.0 ), and the OPTION of recording with it, than without, at what remains excellent value for money on a per-amp basis.
I can understand your frustration, I just don't agree with it, and that is just my opinion.
