Should I go with Vector or Fitbit Blaze?

[passin]

Like the title suggests, I'm looking to step into the smartwatch world with W10M. I am attempting to choose between Vector and Fitbit Blaze. I'm leaning towards vector due to the long battery life and less frills but I'm worried at some of the reviews about bugs in the app for windows phone. That is where the Fitbit Blaze steps in which has more than I would really want but if it works better then why not. Any input would be appreciated.
