Absolutely, the Hilti is an excellent all rounder and, if their other tools are anything to go by, will be very hard wearing. As good as the rail saws are I wouldn't want to take mine up a scaffold and start cutting a stack of birdsmouths for instance or cut the ends off rafters.
However as I already have a normal circular saw for this use I went for the Makita, if I didn't I'd be struggling to find a case for not taking the Hilti
