I tend to agree that the infrequent traveler that wants to collect points does best to forget status and chase the best promos. That's essentially what I've been doing. I get about 20-30 nights a year in hotel stays so its not easy to get good status with my stays. I use tricks like credit cards and short cuts when I can find them.

For example, with the SPG AMEX you can get benefits without earning status. With the PC Visa you get Platinum status. Depending on your spend you can get Silver or Gold with a HHonors AMEX.

If you earn status with another loyalty program Club Carlson is good about status matching (best bet is probably getting Platinum with PC (easiest) and you'll get Gold with Club Carlson). This is only good for a year or so, but can be useful.

HiltonHonors has an MVP and other fast tracks to Gold.

Marriott Rewards has Gold and Platinum challenges (call their customer service numbers to sign up).

All that said, for the infrequent traveller wanting coverage in as many areas as possible, PC is the right one in my opinion.
