Favourite Part of Unfinished Tales?

[Tuor in Gondolin]

There are any number of the tales that are interesting and
bear rereading. Tuor's is quite enlightening but also
frustrating...with the tale ending just as he enters
Gondolin. His journey there has so many neat bits:
his "chance" meeting with the two elves, his meeting
with (Ulmo?), and his almost encounter with Turin.
A continuation of the tale with his encounters with
Maeglin and "Escape from Gondolin!" would have been
fascinating.

But then again there's the great elucidating on the Rohirrim
organization and the Battles of the Fords of Isen.
And the runup to TH "An Unexpected Party" with Gandalf's
difficulty with Thorin.

Also one other bit, it strikes me that the way JRRT presents
both sides plusses and minuses in the Erendis/Aldarion
disfunctional relationship is not unlike the various arguments
for elves, men, dwarves (and a hobbit) to the treasure of
Erebor after the slaying of Smaug.
