3590 is fading technology, especially 3590-E drives. 9840C is currently produced and supported. I would worry about End Of Service date. 9840C has significatly shorter mount time (time to first byte). Sometimes it is a key factor. BTW: Your configuration describes 3494 library, while you didn't mention
whether competitive offering includes robot. Obviously ATL is a big advantage, despite of drive or interface speeds. Assuming both configuration includes robot, I would vote for STK.
