Of course, because it's removes sub channels from sectors. And it's increases reading speed, because iso loader doesn't do it himself.

repack_gdi for me always produces smaller sizes ~10-20%, and sometimes 6mb vs 1gb..., and its always more convenient to have one iso instead of folder and 5 files. And you can compress too.

With SD mod, i'm yet to find difference in compatibility and speed between those two methods.

Is optimize_gdi better for g1ata mod? Or some games won't work with repack_gdi?

In general for playing games, no serious difference between repack_gdi.bat and optimize_gdi.bat.
But with repack GDI you will hack LBA in game binary, so in some cases you can have problems with it. Optimization of GDI doesn't change anything in the game, just cleanup RAW sectors.
Original GDI tracks have empty padding sectors, it's necessary to move the game data to the disk edge for more fast reading. For ISO Loader it's not needed in general, so repaсk GDI can save a lot of space.
If you compress original track or repacked, you don't see big difference. Empty sectors very good compressed.
