Both designs use aluminium cones - is that something you desire?
Metal drivers have a distinct advantage in stiffness, however, be aware that all drivers ring (like a bell) and that metal drivers ring at 10dB peaks versus the 3dB peaks of non-metal composite/woven designs. Some designers use notch filters to reduce the ringing peaks in metal drivers. Just make sure you are aware of the trade-offs, as these are both expensive designs.
