I've never flown Olympic, but I have had the opportunity to spend some time in BusinessElite on 4 Atlantic crossings this semester, and I wouldn't hesitate to reccommend it over Olympic. The product was pretty nice... the biggest shortcoming is the 2-2-2 configuration, which is not as comfortable in the 767 as in the 777, but it's the best you're going to do in Business. The food was decent to pretty good, and the flight attendants were outstanding. I'm not a big fan of Delta's in seat video system in BusinessElite because it runs preprogrammed cycles, vice the on-demand systems that some other airlines (like AA) use in their premium cabins. I'm not sure what Olympic has for personal IFE, if anything, so Delta's system may not be bad in comparison. All in all, I'm sure you'd enjoy your flight in BusinessElite and I'd reccommend trying it.
