I used line6 podfarm for a loooong time. And to be honest it's perfectly adequate. These days I use guitar rig by native instruments just because I have komplete 10 and it feels new and fresh(to me), but it basically does the same thing.
The only people that will complain about your tone is other guitarists. But if your music isn't for them...just choose something that will put you in the right ballpark and your listeners will not know the difference.
