I see that on some areas MapBox images are the same as Bing have.
Specially on your area - MapBox still has this huge cloud, so here Bing images are better.
In the more detailed zoom levels, it unfortunately just shows an outdated version of BingSat. A shame, it has been years since BingSat has been updated for some really problematic areas (like eastern Petah Tikva).
The best way to check the new images is on construction sites.
In my checks the bing sat- images from Bing are always newer or the same as mapbox.
In Eilat, BeerSheva, Yerushaliyim, Nes Ziyyona have better images in Bing than in mapbox.
Interesting, north of TelAviv the Mapbox satimages seem the same as Bing.
