There is no difference in seating ergonomics between the two bikes other than the different risers (easily changed, you can install XC risers on the Roadie) and the different handlebar.
A lot of people actually dislike the XC handle bar compared to the Roadie's, so it's worth sitting on both to get a feel which one you like better. I think both handle bars aren't really well shaped, but the Roadie's bar is better for me after installing the XC risers.
Seat to peg distance is exactly the same between the two.
The main differences which can't be changed easily are:
1) Suspension, the XC is not only longer, but also better. It's a bit soft for heavier people, but definitely better than the Roadie. On the Roadie you have to spend some money to get it up to par, or some more to make it better.
2) Ground clearance, due to the larger front wheel and the longer suspension, the XC rides higher which means it can potentially clear some rocks or ruts better than the Roadie. Though I have to admit, if rocks and ruts get that big, I'd rather be on a real off-road thumper than on either of the fat Tigers.
3) Wheel stability: the Roadie has cast wheels, the XC spoked rims. The chances of damaging one are higher on the Roadie, though again, in a terrain where that might become problematic I personally don't want to be with either.
4) Tube vs. tubeless: Roadie has tubeless tires and rims, XC needs a tube. Upsides and downsides on both, but it was the main argument for me to choose the Roadie over the XC. I plain don't want to deal with tubed tires and I freaking hate cleaning spoked wheels especially if the bike has a chain.
5) Some useless add ons like the flimsy handguards on the XC. Not worth a second thought, I'd replace them as soon as the bike is home.
It really comes down to whether you want the advantages of tubed tires on 21" front spoked rims, or the advantages of tubeless, 19" cast wheels. Everything else can be changed easily (though for some money).
