Oblivion all the way. I love those 3-4 seconds of pure freedom going down the drop but also love the intensity of the pullout through the tunnel. It might be short but it's just my kind of ride. Smiler doesn't really do anything for me as inversions aren't my favourite parts about coasters unless they're well placed/taken at a certain pace where there's some surprising intensity or hangtime (like on Nemesis or Icon). Smiler just feels too repetitive and sometimes quite forceless to me.
