Elgg Orkut or BuddyPress CosmicBuddy

I usually don’t post my most difficult questions in my blog, due to the fact that I’m the one who is supposed to sort it out and THEN post about it. This time it’s different.

I recently made a post about the new Elgg theme Orkut, which I’m using in my new blogging network, but shortly after I discovered CosmicBuddy, the BuddyPress theme. Now CosmicBuddy provides everything that Elgg already had, which made me use Elgg in the first place.

The question is, start over with BuddyPress and the new theme, or stick with Elgg, and a much easier to use Admin interface?

If you think you can help me solve this question please drop me a comment.
