I wouldn't use a journaling file system on USB sticks, it adds a bunch of unnecessary writes.
For Linux only USB sticks, I use ext2.
Better ext4 without journal:

If you are using SystemRescueCD-1.2 or more recent, it's recommended that
you use an ext4 filesystem with the journal turned off (this is possible
with Linux >= 2.6.29). USB sticks are Flash filesystems and this type of
memory only supports a limited number of writes.
Journaling filesystems will make many writes at the same location (where
the journal is stored). Therefore, to extend the lifespan of the
memory we should limit the number of writes. Here is how to use ext4 with
the journaling turned off:
mke2fs -t ext4 -O ^has_journal /dev/sdf1
Note 2016-03-12: tune2fs -O ^has_journal
