TL;DR: I've done the 'verb trick in POD Farm and IMO it's no revelation, IMO. If it works better for you, that's what you should use.
POD Farm owner, Helix Floor/Native owner here. There's no special sauce in POD Farm, some of the sounds are good (bass especially), but nothing you can't get out of Helix. As far as a "feel" thing, there's no way anyone will ever be able to confirm or deny if one or the other is better. The real answer is up there in "if it feels good and inspires you to play instead of tweak, that's the better sound for you". I can't get ANY feel out of POD Farm no matter what settings I use, sounds like a picture of a tone on top of a guitar signal while I'm playing compared to the Helix. POD Farm sounds just fine in a mix, especially with some more modern IR cab modeling applied, but to actually play through it the Helix "feels" better to me every time.
