Got 'em both. Virtually identical in quality, but after only six months, I did have to send in my Kiribi after the screw popped out of the arm which snuffs out the flame. Laudisi took good care of me and sent it back in good shape. It's a fairly common issue, from what I gather.
Oddly, if asked which I'd recommend, I'd say the IM Corona, but it's the Kiribi that I carry in my pipe bag. Go figure. Really, it's a toss-up. Buy the one with the features and appearance you prefer.
