After looking at these suggestions - it seems that the Chase Sapphire Pref. is the best and easiest alternative.

But how much of an extra benefit am I getting by switching from Capital One Venture to the Chase Sapphire Pref.?

It seems marginal at best, especially when I also have the annual fee to worry about.

Do you think I should just stick with the Cap. One?

I do like that the Chase cards can have auto pay.
