i'd aim for the new FB engine. it's new and i'm hesitant about platforms we don't know much about (in terms of 10 year/high mileage reliability and lots of quantitative statistically relevant examples) - but it's a seemingly great platform with no timing belt maintenance. and Subaru hit a home run with their timing chain driven H6 engine in 2001 which is one of my favorites.
would you recommend spending the more $ for new forester or is the 2010 one good enough?
both are a great fit depending on YOU.
if the newer engine i just mentioned interests you, that comes in 2011 Foresters. the 2010 EJ25 engine still has the possibility of head gasket issues which aren't a huge deal but if you haven't bought yet and there's a compelling reason to think it can be avoided - i say go for it. i'd lean towards 2011+ Forester (or the FB25 engine instead of the EJ25 of 2010 and earlier).
warranty is nice but not much is likely to happen before 100k or even 150k so you're also not getting much for your money. you're paying a premium for a 0.5% incidence...are you the type to mitigate every tiny bit of small risk?
*if you're the kind of person to say "Subaru is a big pile of junk, i hate this car, and will never buy a Subaru again" when you have an issue, don't laugh as those types of people exist in numbers and post to every Subaru (or any manufacturer) forum online, then you should probably buy new with warranty and mitigate the miniscule risk.
if you're the type of person to drive a car 200,000+ miles then the differences are probably minor in terms of "cost/mile" as most Subaru's can easily do that with minimal maintenance.
