DocuSign works fine, I use eSign which is basically the same thing. There are others as well but I've used and still use these 2.
Check out Right Signature
I’ve used dot loop some. Never had any issues with that or docusign
Just started an Authentisign 30-day trial after testing out DocuSign. Off the bat, DocuSign seems cleaner and more intuitive, but it's decently more expensive. Only around $60/year for Authentisign. I think once I go through a few more signings I'll be fine with using the Authentisign program. I might have to try out a few of the other ones mentioned through.
I've been using dotloop. Its been working great!
Just to follow-up on this post, I found eversign. Free each month for 5 documents as in I can do five separate signature transactions. It works just like docusign without the cost.
I use HelloSign. If you don't do many leases, it's free - I think they give you a few each month, or you can upgrade for a fee. My realtor uses DotLoop and it works pretty well too and has a really good app if you do a lot of this in the field. Normally I just don't have enough turnover each month to spend much (any) money on electronic signature applications.
