What are the state of the art to use vim as a java IDE

I am using vim to code in R,kdb,C++. In my new job I'll start java and I
was hoping being able to keep vim. There are a few similar subject that
are pretty old on SO. Say I want to be able to get
completion (like YouCompleteMe)
snipets (like ultisnips)
syntax checking (like syntactic)
syntax highlighting
I do not want to pay for it (well don't really care but the compny would
not allow it). I know about
eclim
vrapper
What are the +/- are there new contenders ?
