Difficult for me and also a little unsatisfactory,
as the decision in column 4 was not possible for me without a (very long) chain, but then the solver rolls through.
So AD4 must be low

very nice - 2 options for 2 in / diagonal - one option solved with no further chains (I am sure there is also a solution without this guess, I just couldnt find it)

Not so easy this time. One number in D8 led to a quick contradiction..
