Can't really help you with Paradigm.
We have a friend here, who is taking a break from the forum, that went from SVS Prime to Klipsch RP8000F to JBL Studio 590. I think I referenced his experience earlier, but he found the JBLs to be better than the Klipsch. Mind, that particular model, the 800F is probably the best testing of their speakers.
Anyway, If SVS, I would argue for the Prime Pinnacle as the benchmark. It reviewed very well here at AH with very nice Measurements. Those matched with Ultra Center would make for a nice Front 3.
Beyond that, some of the Paradigms are well respected speakers, but the recommended ones get pricey. Their more affordable models seem somewhat inconsistent in terms of overall performance and quality. In fact I think a member here shared a story and photos of a Paradigm purchase that literally fell apart in the boxes!
Anyway, the best Klipsch has to offer is still woefully inadequate in my book. Yes, I am harsh. They have the ability to build a better speaker and don't. They look nice, sure, but if their best falls apart, sonically, in the Midrange where they cross from woofer to tweeter, why would anybody recommend that. This does not seem to be the case with the JBL Studio 5 line.
Those JBLs also use Horn-Loaded Compression Drivers, but in a 2-1/2-way design: everything I've seen and heard from other members is pretty standard: praise. *shrugs
Again, if you want to try them, SVS will ship and pay for returns. All you are out if you don't like them is time to audition them over 45 days. All of their speakers are made to mix and match in terms of SQ and voicing, so the Front 3 I suggested up above could be augmented with any of their other Ultra or Prime line of speakers. Throw in a Sub or two and in one wild shopping spree you can have a very respectable HT set up.
Your next best bet would be ordering through Crutchfield, but you will have to pay restocking fees if you return something. If you want to try things out though, order one each of your two favorite towers and try them against each other. You'd have to call them and ask how that would work in terms of restocking.
What's your actual budget? What are you wanting to build out, or, what is your goal with this purchase?
