Ah yes, the article points to the thread, but the thread pre-dates the article.
Personally I'm not a fan of adding new cloud accounts. I already sync stuff with Google, so GTasks sync is a positive for me (in that it lets me share todos between apps, and hence change apps easily). Or apps that can work without sync are OK. But an app that requires I create an account to do anything probably won't get a fair trial from me.
On the apps described in the article, last time I used GTasks it was fine except that it wasn't good with recurring tasks. I don't know whether it's improved in the meanwhile. Any.Do is pretty, but I find it a bit slow, and the lack of a scrolling widget seems rather old-school. But it does seem to have improved generally in the last 6 months or so. I occasionally try a few ToDo apps just to see if there's anything that works better for me than Astrid (which isn't perfect, but I can work with it).
