Actually, chatting with my wife earlier about this she brought up the issue of banking fees. S-Pankki / LähiTapiola don't charge for online banking, withdrawals and bill payments and have no monthly fees for standard accounts and no fees on credit card purchases. All the other banks do have at least some of these (but Osuuspankki at least don't charge for withdrawal or credit card purchases, but you do pay to use online banking and they have monthly account fees). Don't know about the speed of Paypal transfers, etc, though.
I've been very happy with both so far.
