Is Manjaro really a good choice?

A friend suggested me to try Manjaro, saying it' s good, stable, well updated, etc etc.

I'm an old user of Debian and Ubuntu. Before doing what he suggested i did a bit of search and found massive amounts of posts (not only here) asking for help because of systems no longer booting, x crashes, kernel panics, corrupted filesystems, screwed bootloaders and all other kinds of horrors... Oo

So the question is: is Manjaro really a good choice?

Friend also told an enigmatic thing which i didn't consider at first: just be careful when updating and don't do it often.

How i'm supposed to update carefully?? It's a matter of running a command or not...

Does the system break on every update and you need to fight to get it running again every time?? How is Manjaro different from Arch which is known to be heavily affected by this exact problem?

The other os i was considering installing is Fedora, maybe a better choice...??

The only problematic hardware i have is an Nvidia card which needs proprietary drivers.
