I have the C1 Venture one as well but I don't use it as they don't have autopay feature (or atleast I couldn't find one). With so many cards I prefer not to deal with keeping track of due dates.
I think Chase Sapphire Preferred would be a strong candidate due to no foreign transaction fees. I have used it abroad and the exchange rates you get are very good.
The trio of Chase Sapphire preferred + Chase Freedom + Chase Checking works very well for me. Mommy points has a good blog post about it:

Chase UR portal can yield significant points earnings.
Amex SPG is next on my list as well as the Discover more card due to significant savings through Shopdiscover portal at many places. I think they have foreign transaction fees though
