First, about Bisko, I already had her but got a dupe from my winning E-5C LD run so she's definitely there. It's really important to include what difficulty you're talking about because drop rates DO differ between difficulties. Now, regarding Gotland and E-5, a copypaste of a writeup I did last night for another user regarding specifically Normal difficulty:

Speaking specifically about Gotland and E-5N, I believe J is an easier and more resource-efficient place to farm her than Z2 despite the lower rate, but Poi statistics lists her as dropping on A-rank as well as S-rank on Z2.

Appearances are ~1.3% for S-rank J, ~0.9% for A-rank Z2, ~2.2% for S-rank Z2.

If you can consistently clear Z2 with an S-rank and have the resources to burn, she should appear there sooner than J. It's all efficiency vs. cost. Assuming you did E-4 on Normal too, E-4N boss node has a ~1.5% chance of her dropping on S-rank which may be preferable due to lack of combined fleet leading to far more efficient runs, plus good chances at several Italian drops.
