One uses ESQL, one uses Java.
I'll leave you to work out which does which.....

Prefer ESQL(C.N) than java (JCN) if performance is critical.

I know some Java developers who'd argue with you on that! 
(Rightly or wrongly - I don't want to start a statistics war here...  )
Another point is maintainability. We use a lot of ESQL because we're migrating (at last!) from 2.1 to v6 so we have a large installed base of ESQL to keep going. We also have more MQ people who know ESQL than Java people who know MQ.

Hi!
We have v5 and soon we will migrate to v6.
Is the ESQL (in the versione 2.1 or 5) 100% compatible with the ESQL in v6? |

Depends how the ESQL is written. Experience indicates 90%ish with this site's rather pedestrian ESQL. Check the migration documentation for full details.
Clearly you might want to deliberately change some to take advantage of v6 features.
