I think both the Panache and the Freya underwired are better than Shock Absorber Run, but they're very different styles (and I have all 3, which I wear depending on how far I'm going and how "strapped in" I want to feel!)
The Panache and the Freya underwired are bulkier bras, because they provide all-round support and encapsulate you in cups, more like a "normal" bra. The support is brilliant, but they are firmer and bigger bras for that. Whereas the Shock Absorbers are lighter and stretchier, and don't have underwire as, instead of encapsulating boobs individually, they just strap you down so you can't bounce.
There are pros and cons of both but in general I prefer Freya/Panache for the extra support. Shock Absorber is fine for a more lightweight option.
I've tried lots of others over the years too. People rave about Enell (similar to Shock Absorber, only with hooks at the front) but those bras rubbed me horrendously.
As I have a small ribcage and weirdly big cup size I don't get on with Nike, Ronhill, Brooks and other sports-type brands as they don't tend to be supportive enough in my size, but as a C you may be OK 🙂
