I like how easy it was to use once we got past figuring out all those little things that are so specific about this software package! It's not perfect by any means but has been very useful over our first year or two using it - especially with training new employees who have never used filenet before.
The fact they were able (and willing)to answer my questions immediately when something didn't seem right made me feel more comfortable than if i had just left them alone without asking anything at all haha :) Definitely give some thought into what you want your system looking/functioning exactly as well because there will be many features available through different modules depending upon which version / level plan one chooses from beginning-end up front.
