our office use/recommened terri scheer and EBM when i did property management i preferred EBM, definately go with a dedicated landlord insurer they tend to be better than what normal insurers offer. The biggest catch i found was claiming for malicious/accidental damage can be costly as each item has its OWN excess so 4 holes unless you can prove happened from one incident you pay 4 excess which means it aint worth claiming for.
its all a much of a muchness between those two, id guess our rent role would be a 50/50 split for cover between them
