The two programs are quite different in how they run. YC is very much a case of moving to CA to build something from an idea, then take it on to investors. That's why the program is intensely structured over the several months with specific events and the end demo/investor days. In contrast, Seedcamp runs day events around Europe throughout the year which lead up to the annual Seedcamp Week from which a number of companies "win" and get the investment. Having been part of the 2009 batch and getting an investment with http://www.serverdensity.com http://www.serverdensity.com I didn't even move to London (although I am there now) and there was much less structure than YC has (not a bad thing). I believe the months following the Seedcamp Week are now more involved for the winning teams but the differences are still there. Perhaps that's why many Seedcamp winners tend to already have a product built, revenue and customers (of course there are many YC teams now in the same position). I don't see them as competitors, just different approaches to a similar idea. You have a choice who you apply to knowing this.
