Which is a better deal?

25 Hilton HHonors points/$ per stay?

or

7 Starwood points/$ per stay?

I have this decision in front of me and am not sure which is quite better. A couple of points:

1) I have already qualified for both Hilton Diamond and Starwood Platinum (and above includes their top tier bonuses) so I have no particular goal in either program.

2) I usually save my HHonors points for ALON or other package awards. I usually redeem my Starpoints for American miles.

3) I have no preference between the hotels.

4) I actually also receive about 1000 extra miles per stay on both programs, so I didn't mention it above since it's a wash.

I'm thinking my best bet is to switch back and forth, every night, to get the extra miles per stay and use the perks of both program. The hotels are within a mile of
each other and I don't mind switching. But any other feedback would be welcome.

Thanks
