For high sequential throughput, nothing is as optimized as XFS on Linux yet. It has weaknesses elsewhere however.
I'm curious what you feel those weaknesses are. The recent addition of XFS back into a more mainstream position in the RHEL kernel as of their 5.4 update greatly expands where I can use it now, have been heavily revisiting it since that release. I've already noted how well it does on sequential read/write tasks relative to ext3, and it looks like the main downsides I used to worry about with it (mainly crash recovery issues) were also squashed in recent years.
