I have been reading up a little on file systems having just built an UnRaid server. Curious about file systems, what you like, don't and why.

XFS
ReiserFS
EXT3
EXT4
JFS
ZFS
BTRFS
OCFS2
 
Xfs and btrfs are my go to systems.
xfs for performance, btrfs for features.
 
Always ZoL (well, not practically a Linux FS).
If running VMs there's usually ZFS underneath, then I'll just run XFS in the VMs.
 
Of the 100TB or so that I manage. 3/4 of this is on ZoL with the rest split between btrfs on top of mdadm raid6 and ext4 as /boot and some single drive setups.
 
/ runs ext4 (on a SSD)

everything else is ZFS on a pair of RAID-Z arrays. (though the next one will be Z2) As to why? / I almost don't care about, ext4 is perfectly fine and supports TRIM. The storage arrays are the important bits, I want data integrity above all else, hence ZFS.
 
I run ZFS on my Linux file server because it seems to be the best in terms of data integrity and has great performance and features.
