I agree - Chocolate Soldier is definitely a browner red - and gorgeous to boot. I have some planted in front of physocarpus aurea and I think that is sambucus Sutherland at the bottom
A red I adore is Merry Mayshine -
Super-shiny petals, lovely dissected foliage and it dies down early so good opportunity to plant late blooming stuff behind her - I have heuchera Marmalade behind one of my clumps.
