Those two Chopin etudes are a toss up for the hardest of all (along with 25/11 and 10/2, all IMO), and the Liszt isn't terribly easy either. I'm playing it right now, and there are some tricky sections, though it is by far the easiest of these three. Also, all of those are available here for Gold Members, so I'm not allowed to post links to the sheets.
What's important to think about when choosing etudes to strengthen a specific part of your technique is whether or not you're picking the right etude.
10/1 deals with expansion and contraction of the hand.
25/12 deals with setting the hand and sweeping it up the keyboard, replacing 5 with 1 and vice versa.
The Liszt etude deals almost exclusively with arpeggios that are passed between the hands, so it will do very little for coordinating shifting the hand and moving the thumb in whatever manner you choose (please no thumb under/over debates right now!).
I have no personal experience with the Debussy phil recommended, but the sheet music reminds me of the Liszt in that many of the arpeggios are between the hands (it also looks quite a bit harder than the Liszt). Also, it is the only of these that deal with "regular arpeggios" (one hand, repeating pattern w/o a repeated note).
Which of these, if any, deal with the aspect of arpeggio playing that you're trying to improve? That's the one you should pick, even if you think it'll be too hard for you to play at concert level.
