As the title says, what's the biggest difference? Any first hand experience would be great, and any benchmark comparisons would be great as well (if possible)
 
Solution
There are plenty of reviews/benchmarks out there for PCIe and SATA SSDs, just look at a couple and compare. Long story short, PCIe is faster in benchmarks and certain applications (sometimes quite significantly), but probably won't be noticeably faster than a good SATA drive in normal consumer use.

As an aside, it 32 Gb/s and 6 Gb/s for PCIe and SATA III respectively. Lower case 'b' means bit, whereas uppercase 'B' means byte. One byte is eight bits.
