100/200 vs. 5000 Series

[Sperry, Peter A -Syntegra US]

I realize that both are type 44 cars, but am wondering what was changed,
upgraded, and fixed with the introduction of the 100/200 series?  

I guess the bottom line is: Are the 100/200 series more reliable, better
performing, fewer gremlins, etc. than their 5000 series counterparts?

Are the 100/200's still plagued with bad bombs, racks, door locks &
electrical glitches?  I'm interested in a comparison between the two.
