- Use xsl to customize look and feel
- Information are display instant unless caching enable
- Can display both minor and major version
- Can use Target Audience
- Can only query content same site collection.
2) Content Search Web Part
- Use HTML and JAVASCRIPT to customize look and feel so very flexible
- Base on search crawl so data/information published is not instance
- Only display major version
- Can't use Target Audience
- Can query cross site collection
What i miss the most is Target Audience is missing in CSWP.
