New to whiskey...

I'm new to whiskey. (Or whisky?) And I drink it neat. So far I've tried a few different kinds of single malt scotch. Dalmore. Aberfeldy. Highland Park 12. I'm too old to suffer a hangover, so I stick with the good stuff. I got a bottle of Dewar's. It don't make me sick. But I can tell that it doesn't have something the others do. Any recommendations?
