I've got both - for me every day of the week, Live Gold.
It depends what you want, if you want presets which will give you the basic framework which you can maybe tweak a tiny bit, add some effects to - Live Gold is the way to go.
If you want literally a Naked Amp, meaning - this is a snapshot of what the amp sounds like, then Naked Amps
Austin Buddy will probably hate me for this description, but what I'm saying is - with naked amps, when I was getting completely confused, unable to dial an amp in - Naked Amps worked great, reset my ears, showed me where I was going wrong.
Hope this helps!
