Hello @grantwall and welcome to the Community.  There is a significant hardware difference between the two trackers.  The Charge 6 has additional hardware to record a 30 second ECG and do additional stress monitoring.  Do you want or need these features?

Hello @grantwall 

You might be interested in checking out the reviews done by The Quantified Scientist on YouTube. He does unbiased testing on fitness trackers & smartwatches, comparing their results against scientific equipment. His reviews include sleep tracking performance.

Here are his video reviews for:
