Not yet,
by habit I tend to grab Illustrator when in need for a quick job for a client, because I know it so well, but a couple of weeks ago I was away from home with my surface laptop on which I only had Xara installed. In a lunchroom I could do a correction of something I made in Indesign and could do everything needed and send it from there to the print company.

For about half a year now I save all my work to my cloud space. I have a lifelong 2Terrabyte space at pCloud. That should do indeed for lifelong I guess.
Very reliable and very conveniant: wherever I am, I can always get to my files!

But back to your question: no favorite really; I guess I keep using them all for they all have their strenghts and weaknesses..
