The issue with Glados is that she's stupid and scatterbrained, because she's very much a hack job. She can focus and do what she needs to, she can get revenge on the people who put her into this situation, but her body is limiting. Glados also doesn't actually like you.

Meanwhile, Shodan, while irredeemably evil and incredibly domineering, she can't stop flirting with you. She's smart, evil and totally in love.

Shodan is clearly the superior evil AI girlfriend.
