what u prefer for commuting ,drops or flats?

Angle of attack is the direction the bike is pointing v's where it's going. For every corner there's numerous combinations of lean & steering input which allow you to turn through the same line. Due to the geometry of handle bars using non-natural variations tends to be much easier on drop, hoods & bull horns.

is the effect not one of those things that the better/faster you are the more these things matter and vice versa?

Better as in better bike hander, maybe, not a faster rider. However being able to pick my AoA when cornering around obstructions at lower speeds is something I find very useful. For instance picking a line between a pot hole & a drain cover when making a corner. Narrower & further forward bars (eg drops & bull horns) make the small movement required to balance everything out much easier.

I'm not doubting that and ride both and have some experience of the effects you refer to, plus quite a variety of different handlebars. It's just that at my level I don't find that these differences detract from my riding experiences. In fact I'd say I don't conciously consider them when riding, you just adjust and adapt, but I'm not trying to push any boundaries.
