If you are a newer player/f2p I think probably not. I'm assuming you're talking about the new version of Hiruzen, the Hokage Successor one? He seems like a good blitz or even support ninja but you'd need fairly high power/stats to use him effectively and I wouldn't recommend him as the first ninja to buy after saving your coupons for months. But if they put him in Fuku milestone rewards and you can get him while getting another ninja or other stuff you need then that's pretty good.
