For me they are still the gold standard... they open close and far, light animals and large, explosive initial penetration, with deep secondary penetration.
They are not tacticool, but I'll take them over tinfoil bullets any day... and mono's too.
I agree with Brad. They have been around for a long time and are the gold standard. Of course there are other newer bullets that work well too. But, for me, it's hard to deny the ability of the partition bullet for any big game hunting.
