There's no way to tell definitively without anechoic measurements for both and a properly administered DBT. You could line up a bunch of Polk fans to tell you the RtiA5's are wonderful, and get a bunch of Infinity fans to tell you how much they love their P360/62's.
There are, however, a few things we know for certain. The P362's are three ways, and the Polks are 2 1/2 ways. That means the 362's have a theoretical advantage in that they've got a 4" transducer reproducing critical midrange sounds versus a 6 1/2" in the Polk. And we know that there's nobody better at crossover design and implementation than the folks at Harman, so the theoretical advantage more than likely is an actual one.
Another thing we know is that a plhart, former Harman engineer who posts on this board said that the guy who designed the P362 is one of a handful of great speaker designers. I know from direct conversation that the P362 is well-regarded inside that company as a speaker that delivered a notable price/performance ratio. John Atkinson of Stereophile, after doing the measurements on the P360 said, "This Infinity may be bargain-priced, but it demonstrates extraordinarily
competent loudspeaker engineering. [emphasis mine]"
One last thing we know is that Polk's listening evaluation room is a conference room packed with speakers, and Harman's listening evaluation room is a multi-million dollar, world-class double blind testing facility led by a respected Ph D (Sean Olive, who also posts on this board occasionally) with an experienced staff.
It's possible that the RtiA5's are better than the 362's but it's not likely.
