I love Passier, but look at the seat shape and what you are used to and see if one of them will not work. The passier has a narrow twist which makes for a very close contact feel, but it comes up in front and back more, which might not work for YOU. Any way you can sit in them?
Are those three saddles perchance for sale in Alberta?
Anyways - are you able to try them out on your horse and get a professional saddle fitter's opinion? English saddles are much more finicky to fit than Western saddles as the pressure points are much more specific. I thought my Exselle saddle fit Ronan alright - man, was I wrong... I just had a pro saddle fitter out who took the time to sort me out with a saddle that worked well for both myself and Ronan... Ronan felt like a different horse underneath me.
I would hesitate to buy without trying a saddle period, much less online... especially if it's a one-shot deal for you..
