Personally, if I had to only pick one I'd go with the browns (keep in mind I've only tried the blues and blacks, but I feel as though I have a pretty good idea of what the browns will feel/sound like)
The blues are loud. Too loud for use in a cubicle, even in my office I get the 'crazy look' when someone passes by. The 'click' sound travels very far imo. From what I've read the PCB mounted (Filco are plate mounted) are a bit more muffled, but as far as the Filco goes - imo the blues are only acceptable if you're not at all worried about annoying anyone.
Also I personally don't like the blues for gaming, but this is personal preference.
All of that being said, the blues are awesome for typing. I've read it regarded as the 'funnest' switch and I'd say that's probably fairly accurate.
But... from your post you're worried about noise, so go browns.
