Perhaps if you are considering an airline career RACWA would be a much better choice
The only reason to go to RACWA would be if you want to become an instructor at RACWA, thats about it.
I don't know anyone there that had any experience other than RACWA so unless you fit the club mold it is pointless.
Go somewhere that the instructors have actually had some real world experience and have not heard it on pprune or at the club bar when someone is exaggerating about their war stories 'up north'.
On a lighter note if you are going for a PPL and want a friendly club atmosphere RACWA is pretty hard to beat
