The team at sales assembly has been very responsive in terms of getting us setup with all of its tools as well as providing excellent customer service throughout implementation process (we had multiple issues that were addressed promptly).
I have not used any other provider but am aware they are out there - so it's nice knowing you can switch! Nothing really specific here except perhaps being able to see which customers/companies use what features more often would be helpful if this was an option available elsewhere. It is hard sometimes when working remotely from home or traveling because some things like emailing internal teams take time to get through due to slow internet speeds etc. Also having someone who speaks fluent french helps tremendously since i do speak decent français although english comes pretty easy too now thanks to living overseas :) So far no real complaints about SAAS product itself just how much faster & easier than trying to create my own custom software solution.
