Its all about ratios.
As stated i’m more than comfortable climbing in 32t chainring and 36t cassette, i could swap to a 34t chainring and would be ok.
What i would like is more gears top end. So if i keep the climbing ratio the same, which im happy with it would be:
32/36 10 speed setup is 0.88888
38/42 11 speed setup is 0.90476
Be hard pressed to tell the difference.
But what it does give me is on the descents, obviously an entire gear. So in some where descents are slower ill be further up the cassette closer to a straight chain line and more tension on the chain.
Its places like BPW where im averaging over 20-25mph on the descents this would be perfect for.
