Aura:If vs Styling to show/hide content
Are there any benefits/negatives from either of the approaches below to conditionally show content in a Lightning component?
<aura:if isTrue="{! v.myBoolean }">
The Content
</aura:id>
versus
<div class="{! v.myBoolean ? 'slds-show' : 'slds-hide'}">
The Content
</div>

aura:if causes DOM changes which is costly performance-wise. Use class approach whether applicable. Of course, there are situations where you might prefer aura:if - for example when you'd have to render many complex components in iteration, but that is left for your judgment. On another note, when using class - the body will be initialized immediately, whereas aura:if will initialize it's body every time isTrue attribute changes value to "true". Sometimes you don't want the component inside to be initialized before something else happens.

The benefit of aura:if is it does not even create the content inside its block if the conditions are false, thus it can help you make lightweight applications.
Hiding a div via CSS will still create the block and thus I feel, it will be bad for performance.
According to Salesforce docs
Using the aura:if tag is the preferred approach to conditionally
display markup but there are alternatives. Consider the performance
cost and code maintainability when you design components. The best
design choice depends on your use case.

Difference between those two is that <aura:if/> actually removes instance of contents from your page and slds-hide just hides it from view. Removing contents from page is usually better for optimization but keep in mind that if you re-instantiate them on a runtime they'll be back at the original state (just as you coded them in the first place).
