Instinct 1 + Venu 2s or Instinct 2s

Hi there.I own a first generation Instinct which I use exclusively for training (strength and aerobic exercise). I use it paired to a chest strap, since the HR sensor is very inaccurate in my experience. I’m planning to add something for every day tracking, so I was considering buying a Venue 2s and continue with the Instinct 1 + chest strap for workouts. For a bit more money, I could get a second generation Instinct which should be more accurate than the old model for every day use. The advantage I see to the Venue 2s is aesthetics for more formal occasions. I do wear formal outfits for work and other events, and the Instinct would look a bit out of place. What do you guys think?

Thanks
