For Lightning Migration which framework is best Visualforce with SLDS or Lightning Aura Component?

Hi All,
During Migration from Classic Visualforce to Lightning experience, should we go with VIsualforce with SLDS or Lightning Aura Component?
What are rules we should consider whether to fo with Visualforce with SLDS and Lightning Aura Component

Hi Navin,

As a first step, you can convert your pages to SLDS simply by uploading a static resource with the SLDSgenerated for you, and then adding a handful of lines of code:
<apex:stylesheet value="{!URLFOR($Resource.SLDS213, 'assets/styles/salesforce-lightning-design-system-vf.css')}" /> <div class="slds myns"> <!-- the rest of your VF code goes here --> </div>
Adding just these three lines of code will give you nearly all of the look and feel of Lightning for virtually zero effort. You can even "theme select" by using some special Visualforce, outlined in this article https://partners.salesforce.com/partnerNews?id=a033A00000F2uEEQAZ.

For more information please check with below link. Hope this helps.

Kindly mark this as solved if the reply was helpful.

Thanks,
Nagendra

If you are a migration on to th lightning ii will recommend using Lightning Aura Component as a primary framework along with javascript because the lightning framework runs on the client side .. 
If there are any gaps that are not able to do in Aura Component then use VF pages ...any response styles is fine but recommend to use SLDS

Yes I have migrated all the visualfroce page to Lightning component. Most of thing are supported and for few thing we need to come up with workaround. I have observed that performance of lightning component is better than  visualfroce page having same functionality. Visualforce is taking 3-4 time(Depend on the complexity)  more processing time than lightning component.
