I have the 160 GB version, and it performs as advertised.
As to reliability I have had no issues, when the bug surfaced with the 8 GB issue, Intel was quick to analyze and released a new firmware to fix the issue.
Reading Toms Best SSDs article, according to them Intel is the go-to manufacturer when it comes to reliability.
There was a post by someone with a link to a computer seller that had a table showing RMAs on different components, and Intel was the best when it came to SSDs.
