Bars for me.
I trade with a standard black ochl bar.
Candles do tend to show the emotion of the market more readily, however, I find it easier to let my decisions be affected by that emotion verses just watching the emotion of the market players.
The color in candles evoke some emotional responses. Red means good or bad and white means good or bad depending on your position.
I find it easier to watch the price action with bars, because bars focus entirely on price.
