You have to try them by yourself, but I can give you my feelings, what I feel about them (my opinions only)
SC 207
- better contoured body
- no neck pu - I don't use and like them
- I hate tom bridges
RG 7321
- I'm bored of those RG shapes
- better hardtail bridge - beter intonation imo
In that price range there's nothing special in those guitars, those are low end of Ibanzez and LTD
You have to switch pickups for sure, then those guitars will be much better.
