+1 talk to tuners you may use about UEL headers and E85 use and their experience, if that's not serious then you're just judging based on centrifugal vs. positive displacement. The canned tunes that come with them are fine (and what I'm basing my decision off of because emissions)

I like the JRSC because it seems they have better thermal management (track day bro) and none of the drivability issues the Edelbrock had early on which I think are mostly fixed now.

But the Edelbrock has that low end punch for traffic and cone dodging. I've waffled on the two for years and am probably still 3 years away from doing it. With no serious driving though and the fact that you probably spend 98% of your driving below 5k rpm I'd think the Edelbrock would be more satisfying.
