COM vs. .NET BOE objects

[eyeswideclosed]

I'm using the BOE XI COM objects in the page that handles the report calls, old-style (CreateObject("CrystalEnterprise11.SessionMgr.1"),etc...), even though it is a .NET page and everything is working fine, I am contemplating rewriting it to use the managed .NET references (mySessionMgr = New SessionMgr(), etc..) instead, would this buy me anything performance/resource-wise? I would like it all to be "100% .NET", as they say, but wonder whether it is worth the effort.
