The best thing about ampsim in reason is that you can completely change you're sound without re-recording the entire thing, you can alter duplicate you tracks, change, compare.
Adding all effects, amps, ect on a clean guitar signal post recording is a producers dream.
Plus with the combinator combined to all other effects (RE's or not) and the spliters so you can have way more than dual done, you can have as many tone as you want.
If you cant get a good sound out of this, I think its a lack of experience or patience tweaking.
Not saying you will get the real thing, but you have more than enough options to shape and get a good sound.
