What is the best online rent collecting service?

[Joseph Waitkevich]

My partners and I started out with RentRedi but have had numerous problems in a short amount of time from tenants having trouble navigating and submitting payments to an unhelpful support team as well as long payment processing times (usually takes a week for initiated payments to hit our bank account. 

What are some of the best online rent services that you would recommend we switch to? 

Thanks!
