NTEN (the Non-profit Technology Network folks) did a 2007 CRM satisfaction survey (http://www.nten.org/research/2007_crm) and a 2009 Data Ecosystem survey (http://www.nten.org/blog/2010/02/09/nten-data-ecosystem-report-now-available). CiviCRM was best ranked in the first, and best ranked for orgs 500k in the second, beating out other offerings including Salesforce, Blackbaud, Convio and so on. Well worth the small investment in becoming an NTEN member, but I think the reports are available for purchase to non-members.
