Sonic Pro HDZ waders vs Simms Freestone Z Waders?

I've had two pairs of the Redington Sonic Pro HDZ waders - the four layer ones with a zipper. I've loved them but they dropped the medium long size, which was a perfect fit for me.

Looks like Simms Freestone Z waders would be similar and their mediums run longer, too.

Anyone tried both? Or some Freestone Z fans out there?
