Thats a bit sweeping...

Yes, Marriott points are worth more, but with HH double dip set to points+points, you get more points per $ spent.

Redemption is absoloutely a YMMV situation, once you've taken into account the greater number of points awarded per $ spent, they're not that dissimilar, although I know the Marriott program well so can wring out every last cent from my points accumulation and redemption, hence I will always acheive better outcomes from Marriott. I strongly expect that a Hilton pointshound would say similar, although the recent devaluation has made their task more difficult.
