This is what I have found but don't take it as gospel because there are a lot more versed people than me.
Typically found in lower end cnc kits
lots available as surplus
larger package footprint
more available torque
The only concern that I would have with that kit is the resolution. A lot of people run gear reduction to help the motors out and to gain more resolution. I am going to run 3:1 on my new table and my old one ran 10rev/inch.
