You should ALWAYS first align the aerial imagery to the existing osm data. It seems to be the rule, not the exception, that there is an offset in the aerial imagery.

Please do not align the osm data to any aerial imagery, that just yields a bias.

And additionally I wanted to say: I am delighted with the bing imagery. In my area it is very nice.

There's a longish dicussion on talk-de, I haven't really followed it, but essentially you probably have to do alignment yourself locally.

I played a bit with josm and the BING slippy map plugin, but the
map seems to be mis-aligned, at some zoom level, with the OSM datas

Any idea ?

with the JOSM-Plugin "imagery" you can align the Bing-Maps.

But how do you re-align the Bing Aerial Maps to the OSM data with the slippymap plugin ? I've found no such option (with JOSM 3695 and slippymap 24530).
