If it turns out the 11-46T cassette functions flawlessly for you, then I'd love to hear your view of how it works, how smooth it shifts.
You might be close to the point of diminishing returns, your gear ratio will improve by (46-42)/42=~9%.
For me it's a bit better, if I change the front chainring from 28 to 24 and go from 42 to 46 at rear I should get about 25% improvement, which should be more noticeable.
It's up to you, of course. I will let you know how it works, might take a bit of time though.
