We have the P900 and 950 here. The 950 is heavier but not as ridiculous as a dSLR. My other half used the 900 hiking across Spain. The batteries run down quickly due to the motorised lens especially if you are switching around constantly between little things and birds.
The quality of the photos is not as great. If you are just using them on FB and IG ie small screen, you won’t notice. On a desktop you will.
Will we take the bridge cameras on our next Spanish Camino? No. We are taking our mirrorless cameras with big lenses ( and hiking shorter days!) despite much increased weight ( my camera gear is 2.4kg).
It all depends on what you use the camera for and how frustrated you get with the quality. For the price the 900/950 are great.
