The only difference is the lead finish (which should not matter in practice); see [FAQ] Why does a logic device's part number have an E4/G4 suffix?

Yes. As Clemens said - the difference is the lead plating.

The G3 is tin (SN) plating, and the non-G3 can be in either tin or NiPdAu - depending on assembly site.

The "G3" ensures that you get tin plating.

Everything else is the same, same die, same test program same package materials - just different leadframe plating.
