The Performance's padding is more streamlined, which makes it a decent choice for more petite mamas - they don't feel (or look!) overwhelmed by the straps of the Original.
As for it being "cooler," well, maybe. You're still talking about shared body heat and regardless of how a carrier breathes, you're still going to find that a bit sweaty.
My other caveat is if your DD2 isn't big enough to fit into the carrier without the insert - my DD wasn't until almost 5 months old - you'll need an insert or something to boost her up so she's visible & kissable. I hated the Ergo infant insert - found it way too bulky and it sat weird on my torso - so I ended up just using a wrap 'til my DD grew.
It's a great carrier and has a long life, but I don't know if I'd buy it just to have it, especially since you have an AngelPak, KWIM?
