I am coming from a Galaxy 5 Pro and have worn Samsung watches for many years. This is a solid watch and very similar to the Pro 5, but honestly don't consider it much of an upgrade. The 5 Pro tracked sleep much better. This watch has gaps every night in my sleep and provides bad information no matter how I wear it or how tight it is on my wrist. Battery life is great, but is similar to the Pro 5. It is a great watch, but if you have the Pro 5 I don't think it is worth the upgrade.
