Mainly the improved speed (6Gbits/s instead of 3). There is a possibility for slimmer connectors and thinner hard drives, but otherwise no. What would be "significant" to you? Are you ordering a new drive?

SATA3 is 6Gb/s vs SATA2 's 3Gb/s. Some SATA3 drives can be set to run at SATA 2 speeds and SATA2 drives should work with SATA3 controllers although at SATA2 speeds.

Cables are the same for either SATA2 or 3
