yup, same juice, I use 80/20 juice, i've used many different juices, never had this problem before on the older ones.
Every clearomizer I've ever used has done this, though I started with the R4s. They don't all result in pooling of juice, but they all get condensation around the sides with varying degrees of sizes of drops. I'm not totally sure about this, but it seems like the juices that tend to gunk up the atomizer the fastest also tend to be the ones that end up with pools around the seal. Not sure why that is. Are you using the same juice in the new ones that you were using in the original ones?
If you have a Vortex, you could try using it's mouthpiece. They are nicely designed to prevent juice from ever getting in your mouth.
