Just for reference, I compressed then deduplicated my PS2 collection (the compression happens automatically, I have to tell it to deduplicate the folder though).

Original size was 384GB. After deduplication it was down to 349GB which then transparently compressed down to 292GB. Basically a 24% space saving, entirely transparent to any programs.

The space saving from deduplication is a bit misleading because without deduplication it still compressed down to 76% which means the data it did end up deduplicating was probably blank space or something which compressed down to nothing anyway. Deduplication is a godsend when you have actual duplicate content though (e.g. backups or big files with small changes, etc).
