For me the IHG was my first Chain, they work very well for me. Get more point and the redemption point are less. In simple word more cheaper for me.
also the rate in most of city that I visit are more cheaper then Bonvoy hotels.

in the last two years my trips was in city / country where don’t have IHG hotels but have Bonvoy hotels where I reach Titanium Elite.
i tested for to year the Bonvoy hotel and benefits but I prefer IHG.

Also, I reach the IC Royal Ambassador that was good experience for me.

At the end this depend of the city / county that you visit, where can get better experience/ easy to reach.
