Not sure if you are strictly for those few options only. This is the leather briefcase I have been using in office and on the road -http://www.mulberry.com/#/storefront/c6622/6160/moreviews/
When I decided to buy this two years ago I was projecting to use it for the next couple of decades. I like that the briefcase is still solid, the leather keeps its shade well and the compartments fit my business needs (e.g. I can put in my lunch box w/o making it look bulky).
