One important difference is hotpluggability.
This depends on your chipset. There is a table here listing the supported
chipsets.

https://ata.wiki.kernel.org/index.php/SATA_hardware_features

That page also lists PMP, if you want to attach more than one device to the
same eSATA cable. Although, when I tried it with a dock that has 2 drives,
one drive would have normal speed and the other would be really slow.

But if you would not have available ports, then your motherboard chipset is
irrelevant in this discussion.
