EI are in the process of completely revamping their Premier (business) product - see the thread under EI. If you happen to catch one of the 'craft that has been reconfigured, it knocks the socks off the equivalent clunky old business class on Finnair on their aged MD-11's. The food on EI is also far superior, in my opinion. The Finnair lounges at ARN can be vastly over-crowded, too. Beware, though, that the Iberia connection our of Dub can be nasty, even in business. Still, given the option, and balancing the time I'd spend with the respective carriers, I'd go with EI and IB.
