Tracy, he's saying that paying the $220 for LavaCore is worth it as it's "significantly better" than the cheaper ($100) variants.
I never used LavaCore, but have heard it compared to a 3mm suit. I would recommend booties with it for sure, and possibly even reef gloves. That would help a lot. One thing about Lavacore is that it's not as tight as a wetsuit (normally) and doesn't stretch as much....so you may have a little more water and water flowing through the suit (hence the booties and gloves, closing up the seams a little bit). The biggest thing about Lavacore (to me) is the wind-resistance. I'm cold-tolerant, but on several dives I was freezing my ***** off in my wetsuit when others were SUPER comfy wearing their Lavacore suits. The next morning, their LC was dry as a bone and I had the wonderful experience of suiting up into an ice-cold wetsuit.
