Theres definately no competition, the anthem 1 is much better spec + circa 550$ cheaper if you pay rrp (which no one does)
xtr's nice and ive used it for a couple of years but its got nothing on the new xo triggers and rear mech.
The way i see it you get nicer rear mech, shifters, brakes, forks (r7's look and feel cheap) nicer looking paint job, as whites just too bland (imo)
Only things id change would be -
Bar - FSA K force lite flat cut to 560mm
stem - FSA OS115
seat post - FSA K force lite sb25
cranks - FSA K force
Saddle - fizik aliante (as i cant stand slr's)
Barends - LP Braids Jr.
which would all be at minimal cost as race face gear sells well, especially new
