In lightning line break is applied automatically for each header tag where as in visualforce line break needs to applied to get content in new line.
And in visualforce and lightning the headers tags are rendered correctly all have same size even the headers are different

In Lightning you need to design custom css on your component

Header.cmp
<aura:component>
  <h1>Congratulations</h1>
  <h2>Congratulations</h2>
  <h3>Congratulations</h3>
  <h4>Congratulations</h4>
  <h5>Congratulations</h5>
  <h6>Congratulations</h6>
  <p>Congratulations</p>
</aura:component>



HeaderTag.css
.THIS { 
   
} 
h1.THIS{ 
    font-size:18pt; 
}
h2.THIS{ 
    font-size:16pt; 
}
h3.THIS{ 
    font-size:14pt; 
}
h4.THIS{ 
    font-size:12pt; 
}
h5.THIS{ 
    font-size:10pt; 
}
h6.THIS{ 
    font-size:8pt; 
}
