BobCadCam versus VectorCadCam

I have bought DeskCNC software and controller 2nd. Gen., almost 2
years ago. Unfortunately, I have not yet build my mahine which will
be either a router or an old Mill upgraded to CNC.

My applications will be in 2 fields.

1. making wooden ultralight propellers from raws with max. sizes of
55" x 7" x 3 ". Given that a propeller has 2 symetrical halves, the X
axis may be reduced to about 32", needing some more handling though.

2. make some aluminum parts for small 2 and 4 stroke engines.
Eventually also some made out of steel.

I have downloaded the demo versions of the 2 a.m. softwares. However
having no experience yet, I am not quiet sure which one is the best
CAD application in my case. Can someone give me some advise on which
direction to go.

Also what size of servo motors should I consider for the 3 axis

Thanks
