As a recent Arch convert--or more to the point, someone who's trying it for a second time--my boot time is ridiculously fast. Since it's a desktop, if it's going to be powered down overnight, I go ahead and shut it down, so boot time matters. It takes longer to log in and wait for GNOME to start up than it does to get to GDM. Also, setup was (imho) much easier than it was when I tried out Arch a couple of years ago.
I get many of the reasons why people don't like it, but imho the pros outweigh the cons.
