UFS1 vs UFS2

OpenBSD by default use UFS1 for partitions smaller than 1TB.

FreeBSD use always UFS2. UFS2 uses double the amount of space for inodes. 
basic operation seems the same.

Does it make sense to use UFS1 for small filesystem (on SSD) that would 
have few millions of files. It will take less space for inodes, but how 
about performance?
