How can I compare having accounts at various banks without opening an account?
I think that your best option is to use the internet to look for sites comparing the various features of accounts, and especially forums that are more focused on discussion as you can ask about specific banks and people who have those accounts can answer. "Requests for specific service provider recommendations" are off-topic here, so I won't go into making any of my own bank recommendations, but there are many blogs and forums out there focusing on personal finance.
