Absolutely! The difference is significant. Honestly, if you are not taking your MTB off-road, you should have road tyres.
I remember this one time about 9-10 years ago before I bought a road bike in Tokyo, I joined up with a group to enter a race, (a "flat-bar" race, so normal road bikes not allowed unless they switched over their handlebars!), and I was training with them on my MTB with the nobby tires. I was struggling so much compared to the rest of the team, they were close to dropping me, and then I got around to changing my tyres, and I was then almost the best of the bunch! Such a huge difference.
