I know this thread is very old.... So am I...
Anyway, in regards to CBN wheels... They do have a place in my shop.  They do a great job on supersteels and not having to re-measure everything in between wheel changes is wonderful.  I find I'm always concerned I'm using too much pressure, time will tell. 
As far as every day use, the SG-250 gets the nod.  The reason being it is more "forgiving", ease of changing grits and the satin like finish.  If you look at the scratch pattern from the CBN vs SG under a microscope there is a pretty big difference.  The CBN scratches are deeper and aggressive.  The SG wheel has a much softer appearance.
In my humble opinion, CBN wheels can be a valuable addition to any setup where supersteels are sharpened or you're sharpening several of the same blade. 
I would love to add an SJ to the lineup..... someday.
