Although I haven't conducted a detailed research by any means, my experience since I use Enpass (for 3 years now) has been the following:
- Enpass app has worked for me impeccably, both for desktop as well for mobile platforms; updates have been regular. This has been the case for 1Password as well but on the much more expensive side. 1Password has been also much more aggressive in terms of advertisement. I just have not see a major reason to use 1Password, especially since they recently turned to a subscription based pricing model, over Enpass.
I hope this helps. I took time for a reply mostly because my experience with the app has been flawless thus far; I hope they'll keep doing a good job.
