Talisman ships are definitely affected by experience, as it increases their defense/ECM value.

When fighting talisman fleets, it is a good idea to get as much experience as you can for your ships and fleets. The more you have (assuming the talisman ships are all at 20 exp), the narrower the gap in to hit rates becomes (100% talismans vs. 20% non-talismans could become 100% vs. 40%, for example). Experience still makes a huge difference when fighting talisman ships.

The experience does not help the defense of the non-talisman ships at all against the talisman ships.
