Have not heard either but agree with your assesment that 60W is too low for the sensitivity rating.

The difference between 60 watts and 90 watts, all else being equal, is 1.5 decibels of sound pressure. The difference between a sensitivity of 87db and 91db, all else being equal, is almost 3 times as great as the difference in amplification.
How each amp behaves with the speaker impedence could be significant, but I am relatively confident in suggesting that both would be able to increase power and handle a 4ohm speaker load with little problem.
I use a 60 watt integrated (100 watt into 4 ohm) with speakers that present a 4 ohm load and get way more sound pressure than I ever need...which is to say 98db with no problems. The speakers are 87db sensitive.
If you really want to go loud, the more sensitive the speakers are the better...as opposed to simply increasing the amplification by 30 watts.
