It's not that people necessarily choose IR over RF. Having the remote capable of doing both keeps the same remote usable with receivers that are not RF-compatible, and some people just do not need the capability.
In my hobby room I watch TV while two feet from the DVR. No need for RF there.
In some environments there is so much stray RF floating around that an RF remote is unusable or erratic.
