Online rent collection, cozy vs avail

[Noah Milstein]

Getting starting in buy-and-hold and trying to do as much preliminary research as possible. In the process of getting a first investment property right now. For the time being I plan on doing all the listing/advertising, data collection/analytics (excel), and payment collection myself (paypal/venmo) until I have enough properties that using a service like Cozy or Avail becomes cost and time effective. In the meantime, in my preliminary search for a one stop platform these struck me as two of the better players. Does anyone have a strong opinion on one versus the other or is there a different platform for online collection that you prefer and why? 

Thanks!
