Will be getting a straight pull .223 and am torn between the Lantac Raven 223 and an SGC Speedmaster (I like AR style rifles over traditional

So far it appears to me that the Lantac is much lighter and will be easier to use as a 'run and gun' in various positions (ooh, er missus) whereas the SGC is heavier and more effective at prone shooting but is more accurate.
Thanks
