The tune is nice, indeed!
As far as my experience goes, using synth guitars is always a fail, unless you try to think a different way about them. They do their intended purpose very badly due to full lifelessness. Too many player-dependent sonic features change in a real guitar sound that is impossible to capture.
Used as component sound they can do wonders here and there. Having them in the mix under the line they can beef up certain type of riffs - but only when used along with real guitar tracks.
Still, the best way is to use samples or the real stuff
Funny thing, but Martin Galway did a far better job on capturing the essence than any VSTi

Listening to Times of Lore main tune still amazes me, even after all of them years.
