Intel 510 - If your main concern is reliability over "speed". Intel's have the record of being the most reliable SSD's but aren't necessarily the fastest
OCZ Vertex 3 (recommend Max IOPS) - If you are all about performance and speed!! It is the fastest SSD (outside of PCIe cards / enterprise cards). OCZ has the best track record for firmware updates to improve performance and quickly address any "bugs". Another option is the Patriot Wildfire, which looks to match OCZ's performance.
After reading a handful of reviews (most of which centered on the 250GB versions unfortunately) I'm probably going to go with the Intel. OCZ certain benchmarks better, but "real world" impressions tend to see less of a difference (from user reports anyway). And I hate having to RMA stuff so
