It does not matter, because when the heating is on the difference between the temperature measured at ground, at ceiling, at the edges or at the centre of the room will easily be a couple of degrees or more apart depending on just how significant the temperature differential is with the outside. Have measured, as part of figuring out how the hell to get to within even 3-4 degrees of the same temperature at different places in the same open living areas.
Very few people live in houses that are insulated well enough and with good enough temperature control that they have anything close to that level of precision control over the temperature in their house.
But if it makes them feel better to think they do, then, hey, they can get my kind of thermostats. At last count there are now 5 thermostats on different heating options in my living room, all with 0.1C steps.
Either system is only "worse" when you're not used to it. It makes no practical difference other than when people try to argue for or against either system online.
The only real reason to consider switching would be that it's a pointless difference that creates minor friction in trade, but there too it's hardly a big deal given how small the effect is and how long it'd likely take to "pay for itself" in any kind of way, if ever.
