Yardi has been the slowest and most buggy. Worst websites. Yardi is good at holding data but bad at using it, so 3rd party websites are highly recommended. Not a fan of their CRM.
Entrata was much faster with pretty good websites. CRM wasn't my favorite but it worked and it's been since like 2017 so it's probably much better.
I havent worked with Real Page but I definitely hear it is better than Yardi
Knock hands down has been the best CRM I've seen
Resi has the best websites. I actually turned to the vendor side for Resi I was so impressed and now work there.
