Well, I have no hands-on with a Savage so a direct comparison isn't possible, but I can tell you this - any comparison with Helix to a POD series is pointless, they really have upped the game that much. It's a whole new critter, from tonal accuracy to organic feel it sounds and responds like any amp I've ever owned - and in 47 years of playing I've owned a lot.
Best advice - buy from a place with a decent satisfaction return policy and find out for yourself. It's been (subtlely) acknowledged by L6 that many of the firmware updates have included under-the-hood tweaks of the engine, and at this point it's hard to find a bad sounding amp in the bunch. That's not saying they'd all be your cuppa tea, but compared to the initial release - where I'd be scrolling thru amps going "blech", "why bother", "who thought this sounded good?" - I now can pull up virtually any amp and find a use for it.
Give'er a whirl - my money says you'll keep it...
