I compared each of my 3 sibling's Paternal Phased kits to my Paternal Phased kit and I painted those segments on my profile at DNApainter. You can click on this to enlarge. I didn't include Chr 23(X) in the comparison. As you can see in the image below there are portions on pretty much each of the chromosomes where none of the 3 match with me. (Note: You should exclude the first portions of Chr 13, 14, 15, 21, and 22 which aren't included in testing.)
Looking at these paternal segments of each of the siblings compared to me, there is a range of about 200 cM. My sister and I seem to have gotten a variety of different segments from our Dad. See the comparison of the paternal matching segments for she and I in the image below.
Becca to Marie 1499.9 cM shared 42 segments
Michael to Marie 1662.4 cM shared 45 segments
David to Marie 1712.4 cM shared 48 segments
I used the same process explained above to compare the maternal segments.
With very few exceptions it looks like my siblings and I have received more of the same maternal segments. That would make me think that more of the DNA which Mom had might have been lost. Thankfully she tested so I have her test for comparison to others.
My sister also shares the least amount in common segments maternally as well. Still a good bit more In-Common-With segments on the maternal lines than paternal. My recommendation remains the same. Test as many siblings as possible.
Maternal Overlap with Siblings--Mom(Tested Parent)
Becca to Marie 2473.8 cM shared 63 segments
Michael to Marie 2605.2 cM shared 56 segments
David to Marie 2696.5 cM shared 63 segments
