Howsit guys

I've got around 3 BTC lying around. I'm wondering which of these IPO coins to invest in.

Qora : https://bitcointalk.org/index.php?topic=522102.0
Numus : https://bitcointalk.org/index.php?topic=543503.0 & http://numus.org

Qora has a BETA of their wallet, but it's very simple and I can't seem to get it to run on my VM (I'm thinking about waiting for hit to release first before deciding wheter I should invest or not). Numus, I've already invested 0.2 BTC but I wonder whether I should put anymore into it. Numus seems like a much better choice to me because of their marketing and they seem very professional unlike Qora. Qora reminds me a bit of NXT though.  Both offer escrow.

Also how is the return like on IPO's? Are there any people who invested large amounts into Heavycoin, Reddcoin or exoCoin (successful IPO's from what I've read) and received a large ROI?
