Electric vs Manual RCBS equipment

[MtnMuley]

I recently purchased the chargemaster powder dispenser and scale for my reloading table.  I love it.  I also purchased the case prep center, and really like the primer pocket cleaner, but still resort to the hand deburring tool over the electric one on the prep machine.  What do you guys prefer and why?  Also, I was leaning towards the electric case trimmer that RCBS has, but am hesitant until I hear opinions on how others feel.  Thanks.
