more rigidity=more acceleration
less mechanical advantage(bigger spools/drive pulley)=more speed,less resolution
plastic joinery=less sound
metal frames=possible resonators
most all deltas=faster than you can print
I have to say most deltas are not nearly as rigid as a simple triangular prism made of 1/4" MDF. People love the simple 3 aluminium extrusions frame but we only get away with this lack of rigidity because of the low mass. Of course, this lack of rigidity pays you back with sound reduction. Life is full of compromises.
I can't really speak to which one is the most rigid. I would have to say I would design my own. On the low rigidity but adequate side, check out the frame on LISA Simpson. (Video linked in my signature below.)
Idea: I always thought it would be fun to make an fold down delta. With a magnetic effector you could possible fold everything down into a super compact linear configuration. (I wish I had time for this but I feel that the column delta space is very crowded with many competent designers. I want to push the envelope with the railless printers.)
