Reading the thread, and the many like it over the past months/years, may yield a clue as to why you wish to move on to something other than Linux RAID...
IMHO, in almost all cases - at the end of the chain - is misinformation. While this might be a bit bold - a lot of users don't even spend a few minutes doing elementary homework like man md/mdadm/mdadm.conf and less /usr/src/linux/Documentation/md.txt. Be it normal usage, or when problems happen. Rumors and forum wisdom can be really damaging - not to look far away - how many people keep believing that xfs eats your data and fills it with 0s ?
It's hard to find cases, when md driver or mdadm was really at fault for something. For the most part the typical route is: [bottom barrel cheap desktop ]hardware/[terribly designed sata ]cable issues -> a user applying random googled suggestions (with shaking hands) -> really, really bad problems. But that's not md's failure.
I'd put lots of responsibility on [big] distros as well, which have been trying (for many years already) to turn linux into layers of gui/script wrapped (and often buggy) experience, trying to hide any and all technical details at all cost. But that's OT ...
Be it flexibility, recoverability (with cooled head and after panicking while being /away/ from the drives and md) or performance (especially after some small adjustments - namely stripe_cache_size for write speeds) it's hard to challenge md. And some awesome features are coming too (e.g. http://thread.gmane.org/gmane.linux.raid/34708 ).
