The trigger controlled 4&1/2" grinder is safer- A young fella was my helper
at a demo and when the grinder wrenched itself from his grasp it didn't shut
off as is the case with the trigger switch- it knitted him a sweater, cut
the cord and we had some exciting pyrotechnics that for a while.

Similar thought here.  I've long used a disk-like wire brush on a
fairly speedy end grinder but last year I spotted a cup brush for
cheap and put it on by 4-1/2" angle grinder.  It worked but it scared
me.  The brush wasn't perfectly balanced so it vibrated more than I
liked and the wires splayed visibly.  Were a bunch of wires to come off
at once, it would just vibrate completely out of control.  Toooo fast.

The same cup brush on *slower* (and, as it happens, larger) angle
grinder works fine and doesn't scare me.

I haven't had a wire brush accident worse than a wire embedded in my
knee 1/2" and I'm real eager to keep it that way.
