Basis table or SME

I am looking to acquire a high end table. I currently use a Forsell Air Reference. I really like the build quality and support that Basis provides and have heard equally good comments about SME tables as well. I would appreciate your feedback on both or either of these tables. I'm considering a Basis 2500/2800 Signature or a Basis Bebut Signature or an SME 20/3 or 20/12. I am open to other suggestions that are designs based on proven technology with excellent customer care. Thanks very much.
