Yes, SK would earn more miles but it does not serve BKK and generally their presence in Asia is very limited. TK serves both BKK and HEL, has 2 year status validity and offers upgrade vouchers to their top tiers while SK offers status gifting which I do not require as I travel with my wife so we both have the same statuses.
