Given the research you are doing, I am sure you will be happy with your final decision.
If you want to throw another variable in, there is also the Plug-in Prius. Smaller electric-only range (subsequent driving is hybrid) than the others you mentioned, but with a lower price (starts at 32 k).
Pros are far better gasoline fuel economy than the Volt, lower price and a shorter charge time. The tradeoff is a smaller battery capacity.
