Not always! Sometimes bigger damage comes at a trade-off for penetration, and vice versa. Derp guns, for example, always have higher dmg but lower pen.
Also, the smaller guns have a better rate of fire and usually are able to put out more damage over time. For example, I prefer the 57mm gun on the KV-1 over the 85mm gun.
