The top of the pass is higher than the ski centre - you drop to the ski centre buildings if coming from the south. So climbing the Cairnwell from the pass is pretty much the same in terms of height gain as climbing Carn Aosda from the cafe. The former (according to my ancient Pathfinder map) is 665m up to 933m, ie 268m, while the latter is a touch over 650m to 917m, ie just under 267m - close enough that it makes no odds.
The Cairnwell route is shorter in distance and is surely quicker, especially as the Aosda direct route involves weaving through a couple of ski fences which don't always have gaps where you want them. When I was young and keen, 30 years ago, I once walked up the Cairnwell from the top of the pass in 14 minutes - I'm pretty sure the same rate of progress would require longer for Carn Aosda from the cafe.
Both hills are better, if longer, from elsewhere - the Cairnwell south ridge is a pleasant way up/down, as is the Aosda north ridge.
