I'd say E70
i was in this (exact) same situation before i got my e70!
my friend has an RRS and hez not happy with it, you see a lot of ahppy E70 customers here!
by the end of it, it's your choice, test drive both vehicles and get the one you feel more comfortable in!

although the rrs is supposed to feel sporty, it does NOT!
e70 moreover is very sporty!

it's your choice again! think immensly before choosing the car you want. you dont wanna make a bad decision so study both cars!
cheers!
