I use the iOS Dropbox client mostly for uploading & syncing pictures and videos between: iPhone, iPad, desktop PCs and laptops. Sometimes for checking files in my Dropbox folder.
Dropbox works well on all three OS I use of which Linux is my main. I don't know what iCloud and Photostream (no syncing of videos?) are like now but it didn't really work well when it was introduced and I'm taking a guess it doesn't work on Linux natively.
I guess I'm the reverse of you: I've already got photo and video syncing with Dropbox so why use Photostream? If that feature wasn't in Dropbox's client, I'd rarely use the client.
