It changes all the time as you have seen. You will have to decide if the benefits for sticking with one brand outweigh the lowered cost of switching around. The answer depends in part on how many nights/stays a year you accumulate.

Hilton Gold is worth getting for sure for free breakfast and internet and reduced price award stays.

Wyndham has a good targeted promo now for some locations.

As mentioned, Choice hotels can be quite crummy. "Quality" Inn has the most misleading company name in the US. But 8K Choice for 2 stays is pretty good. Equals WN 2400 CPQPs.

Most standard hotel offers are 600 WN points per stay, worth $10.
