Which Messiers Are The Brightest?

I live 42 degrees North and live in alot of light pollution even at my dark places the sky still has a bit of glow. Which deep space objects are the brightest and easiest to see from my latitude. I have an Orion ultrablock filter and a 10 inch reflector. I have stellarium so I can find where these things are at but when you select show nebula and deep space objects there are like 100 possibilities most of which I need darker skies to see.
