I'm going to answer the question directly and then follow the larger question as everyone else has -
RIPP sounds and looks 'cooler' for the show kids since the intercooler is more discernible in the front and it makes more turbo noise. I've heard good things about their support. The roots style SCs like Edelbrock/Magnusson make more lower end torque than the Ripp and have less lag and I have had good support from Magnusson - just answering the OPs question directly.
Overall, if you have a 3.73 or other stock ratio and haven't regeared, yeah that's more important to start. I was happy with the pep of the 4.10 Rubicon gears with stock tires but add bigger tires and it needed regearing. So, look at other mods for better spending of money before a SC if you haven't.
On the v8 vs SC answers given here, as an example, I got a deal and spent 3k on my Magnusson SC and have used the heck out of it. For 3k, adding what the Magnusson did, - even in Moab... - helped push my 41.5 Pitbulls nicely. As an example, I got a little too happy with skinny pedal here on the Rusty Nail Trail in Moab -
Everyone has a personal opinion like everyone has/is an ass.

Is it an LS? No. Is an LS better than a SC? Yes. Just like a Corvette is better than a Chevy Cruz. Would I like an LS? Sure. Am I going to spend $15-20k on an LS on a 2yr old Jeep? No. Has the SC been worth it for less than I spent on beadlocks and tires? Yes. Will I swap to an LS when the 3.6 craps out? Yep. Hopefully 3-4yrs out and they'll be a little cheaper since everyone will be JL crazy by then. Not looking forward to all the ancillary costs that will go with the LS also - Regearing axles, Atlas changes, driveshafts, etc.
Just an example and another opinion.
