We utilize LightSpeed and SQL Server Native Backups.
We used LS for the now out of support SQL/Server 2005 systems as well as SQL 2008 (before MS added backup compression to all versions for free). I have used the LS extractor.exe utility to convert LS backups to a SQL Native backups for vendors and systems that did not have LS installed.
We don't use maintenance plans as we use scripts for DB backups.
