I didn't have a problem with either approach. With the 146 the thrust levers are never all together so you can't forget which ones to push up from idle.
I suspect the gear horn had something to do with that on the Dash 8.
But anyway, operating the two throttles together is the ergonomic thing to do. Operating one is very awkward. Keep in mind that most aircraft has the GA button on the outer side of the throttle where the thumb would fall. If the engine fails on the side of the PF, pressing the opposite GA button becomes awkward.
