The DC6-90F is a nice little upgrade from most other daisy chain power cables.
The 90 degree angle fits better between pedal with the power jack on the side and gives you a bit more clearance on the back of your pedal chain (saving the power cable and pedal power jack).
The leads between each connecter are a little longer than other daisy chains allowing you to chain larger pedals or have a little more space between them.
The caps that come with this daisy chain are also really nice. They stay on really well and are a little more robust than other caps. (A little thing, I know, but nice all the same)
Also, the connecters themselves are just a little longer, so if you have a pesky pedal with a deep power jack, these will get in there.
Compared to other daisy chains, I can't find any cons with the EBS DC6-90F
