This is likely not so popular here, and I have been using it much less since LR3, but you may consider ACDSee as a image manager.
Or MediaPro, but I have had way too many issues with Media Pro.
If C1 had the interface and features (Export/watermark) and EASE of use as LR, I would stick with C1. C1 interface is so "proprietary", that you have to shift your way of thinking, where as LR is logically generic in the interface to OS, or PS, etc.
I DO often end up processing "important" still life work in C1, and "people" work in LR. There is a clarity I get in C1, And I am not sure if it is measurable, specially with improvments in LR, But I work less to get the clean 3D clarity I like in C1, and the colors I love for C1 for Still Life...oddly I will take LR colors for converting to BW over C1.
Hope the above doesn't confuse you more, but I hope it gives you info of an approach that may help you choose.
