Hi, these are just my personal experiences with the Versa (updated to the latest Firmware version):
1. Step count: accurate
2. HR: seems accurate to me, only needs some care once and a while, e.g. cleaning the sensor.
3. Sleep logging: no problem
4. Exercise logging: no problem
5. Active minutes: sometimes it misses a walk
6. Battery: mine lasts 5,5 days on one charge. Mind though that I do not have music on it and only one notification enabled.
7. Syncing: in principle no problems, but sometimes you have to do it manually, certainly when you are way out of BT range without your phone in your pocket.
Once again, these are my personal findings. Good luck with your choice.
BTW, before you buy one, see whether Fitbit is supporting your phone by looking at this article.
