TITANIUM: RME or MOTU

Just got one of these Grey classy too expensive machines.So after a steep research
into the soundcard scape, it seems to leave 2 of them for me: RME multiface with the
PCMCIA card, and the Firewire MOTUS 828 and 896 or something (the 96KHZ one).
I would like to get feedback about them with mac machines.
I am also concerned about the fragility of the connection between RME PC card and the cable to hardware interface..So that applies to PC users as well i guess.
I plan to MOVE these babies about town, you understand...
