Dogecoin has only one advantage: Elon Musk tweeting. If Elon Musk loses interest in Dogecoin so will everyone else. Cardano on the other hand has a whole team dedicated to marketing Cardano and improving it.
Really? you would compare Dogecoin to Cardano as you can see the Cardano has a really use and really a project not unlike the Dogecoin that was controlled by the influence of Elon Musk as you can see the price goes pump and dump in just a matter of days or hours, in real life the Dogecoin does not have use at all and just created as a memecoin and that's all.
So to answer your question of course Cardano is way more better than Dogecoin.
