Clark was the name of a cousin of mine who died last year (we were the same age: 30), so I have some sentimental attachment to the name, even though I never would have considered it myself with or without knowing him. To my ears the sound is very harsh and hardly sounds personal enough to be someone's personal name. One of those cases where it sounds like you're constantly calling someone by their surname.
The sound of Roy has never appealed to me. I don't like the "oy" sound at all. Not that big on Joy or Joyce either, come to think of it.
Real life brothers Clarke & Roy, while very far from the worst sibset I've seen, sound incredibly preppy. Like they're going to grow up and play tennis with Penn, Spencer, and Thatcher.
