One can not generalize like that.
A high AR foil is NOT a foil that is a lot more difficult to ride, nor does it start later or stall easier.
But reality most often is, that those making high AR wings choose a race profile and smaller area, and voila - you have created a thing that starts later and stalls abruptly.
You can easily make a high AR wing with more camber and more area - and it will start ealier than ANY other wing, and go the highest angle to the wind (but not max VMG), that is for sure
Just saying, that "AR" is not really a parameter you can use alone.
Would be better to talk about "race wings" instead.
These are typically smaller in area (unless in really light wind for upwind), and a less cambered profile, and quite high AR
