Prove it. I've had no reliablilty issues whatsoever that were due to HFS.

Define "big". I know quite a few people with multi-terabyte systems on HFS+.
OS X and HFS can handle large filesystems quite nicely.

Backups are another way to never have to trust your file system. But I have
yet to see hard, reproducible data that says that UFS is noticeably more
reliable than HFS+.
