I've had quite a look at btrfs on my machines and I'll some up my results in a (very brief) Pro's/Con's list
Pros-
Faster in certain circumstances
Snapshots and snapper is awesome
"It's the future"
Cons-
Slower in certain circumstances (like every benchmark and every 'real world' test I've tried. Slower boot times, etc)
SSD performance seems to be variable depending on your SSD and how you tweak btrfs
no fsck / only just introduced - It doesn't 'feel' ready yet
I totally understand anyone who goes for btrfs, those pros are pretty nice and shiny new stuff is always fun
but for now I've decided to stick with ext4, it's stable, it faster than muck through a goose, and it does everything I need it to do, if not everything I want.

I;'m having btrfs and frankly it's a pain on this SSD. Might be different on a
hard drive, but be sure not to come even close to running out of space as
btrfs does NOT handle that very well (gets extremely slow). In general I'm not
happy with my choice, even the latest kernel in 12.1 does little to alleviate
the pain.
