If you know how you sleep in EN rated bags you can make a good comparison. I sleep pretty close to EN ratings assumed proper fit.
The shell on most high end bags does a good job repelling minimal water such as spindrift , light rain etc . Use a bivy for more protection , or if you need a big garbage bag over the foot end
