Howard, I've used both and I find BasicColor VERY easy to use, both for profile creation and profile validation. I don't see any one the least bit serious about doing this job (and remember the O/P is a serious professional) having a problem with either software - i.e. to my mind not a reason to chose one over the other. When I first bought my NEC PA271W it came bundled with Spectraview, so I calibrated and profiled with that. It was OK, but I wasn't fully satisfied with it, so I tried BasicColor 4.x.I found the validation outcomes better, and using this software I more easily achieving a screen to print match, so I stuck with it. Now some years have passed and things change, so whether this comparison would remain valid today I can't say for sure, but for what it may still be worth, that's my experience. As I said above, there's nothing except a bit of time to lose trying both and seeing which satisfies most.
