A personal recommendation is actually to use both, goals and funnels. The key a funnel is that you need to have successive steps that occur in some order. With regards to metrics tracking this is absolutely needed, but typically you may have 1-2 total funnels with many steps in your site versus goals where you could have 10-15 single goals. For Registry Stop we’ve structured our site so that our earlier stage goals become the same as steps in later stage funnels. For us in almost all cases the first part of the funnel is the visit, the second is registering for an account. We do have independent goals for visits and registrations as well, but we do not have funnels on those goals.
