What problems have you had with Cherry Laurels?

Hey guys. I want to plant some 3/4 foot cherry Laurels in my front garden to block the road off and gain some privacy. I’ve seen mixed reviews on Laurels. Before I buy them, I was wondering what problems some of you may have encountered with them. I want a good, reliable, dense and tall hedge eventually. One that doesn’t take too long to grow, and affordable as it’s quite a big garden out front so I’ll need a lot. Thanks guys!
