I listened to TGM, and it does sound cool. But, it does sound digital, it does sound fizzy, and it does sound like a POD. It doesn't sound like an amp to me at all. There is no depth, no image.
But, what we are talking about here is using a POD as a DI for reamping. The conversion in the POD sucks the life out of the guitar signal.
Unless you have a POD, some quality DIs and some quality converters and can run your own tests, it is all conjecture, and just seems like POD self-defense. I have a POD, and I have good DIs, and I have reamps, and I have tested everything and I can tell you it didn't take any critical listening to be able to hear the differences with these things. It's really very prominent and obvious.
Here's the thing: If all you have is a POD, then by all means use it! It's better to use it than not. Don't think "I'm not using that, because it's a POD, and I am going to wait until I get a real DI". That is a waste of time and resources! Use the POD and while you're using it, save for a dedicated active DI. It is folly to spend $$$ on your pickups, amp, recording chain, etc if your DI/converters are taking the life out of the signal. Upgrade one thing at a time, but don't convince yourself that the POD is "good enough". There is a reason why people use quality gear, and it isn't to show off.
