Hi Felipe, 

I do it a different way. I am using Osmand with Google Satellite Aerial tiles and hourly updates. 
The current OSM data corresponds quite good with the Google tiles. 
So I use this a reference, but of course can´t use Google Satellite in JOSM. But I with a bit adjusting and verifying my changes in Osmand I could manage to realign a few things. And I can apply an imagery offset to Bing or ESRI. In the end I have to decide for the imagery, to which the already given OSM data corresponds most. 
However, I focus more on adding businesses and such, because this is more important for other travelers and other apps and website, which are using the OSM database. 
The realigning was just a bit trying out. But well, I am going to check with Strava, but don't understand why Strava. Is there any reason? 
Saludos, Andre
