Really stuck on this one for the first time in a while. Had to use hypotheses rather than pure logic at one stage. Nice puzzle, thank you.

I couldn't solve this with logic: had to use trial and error. If you did manage with logic alone, please tell me how! Thanks
I can place three 5s, three 4s, and two 3s relatively easily (let me know if you want explanation of how to get this far!)
Then, where's the 1 on the bottom row? If it's in front of the 4 clue, that column goes 1 3 2 as we work up, which means row 3 goes 1 5 3.
If it's in the middle of the bottom row, then the 5 must be immediately above it, and so the second number in row 3 is still a 5.
And since the only possibilities for the second number in row 3 are 1 and 5, that means that this spot is a 5.
The rest of the solve is pretty straightforward from there, I think?
There are probably some other logic paths that give the same conclusion, that the second number in row 3 must be a 5.

Just looked at the comments here, and I redid this one to figure out the trick. Took me a while (and I think I did trial and error when I first solved it, too).
Do as far as joshuazucker said in his first sentence. Then eliminate all but one 3 in column 2, using the 3 clue at row 4.

Key
A yellow/light blue highlight in the time distribution charts highlights your time, where relevant.
Rating scores out of 10.0 show the average difficulty rating chosen by users, where 1.0 is "Easy" and 10.0 is "Hard".
If a puzzle is opened more than once, including by loading from a saved position, then this is potentially a significant aid so it is listed as being completed with 'multiple sessions' for the purpose of the best time/average rating displays above.
Minor aid is defined as no more than one use of 'Check solution' when incomplete and/or no more than one use of 'Check solution' when wrong; and/or using highlighting aids (show repeated digits, show broken inequalities and show valid/invalid placements [slitherlink] only). Major aid is any and all other use of the solving aids except for 'show wrong'.
