I'm looking to buy a cheap guitar and I have these two choices. The 370dx ( pre-used ) looks like it beats the grg all day but when I looked, the newer 2015-2016 model of the grg270dx seems to look good good as well with the upgraded tremolo and infinity pickups.

You guys think the brand new grg270dx would be better than a used rg370dx? I don't have much options here in my current area so I only have the two at the moment.
