I have 8 horses and in Hungary none of them are shod. The same cannot be said of the same 8 in the UK - at least 3 would have shoes on with the rest having a sharp eye kept on their feet . The farrier I get advice from ( I barefoot my own with advice ) will tell you that climate has a lot to do with a horse needing shoes or not.
Hungary is mostly a warmer drier climate than the UK - the UK has rain almost every week - Hungary can sometimes go for 2 months without any, so the horses feet in HU have less moisture in them and are as hard as nails.
Barefoot Vs shoes is a bit unfair as much depends on climate / horse / work ethic - so both are good in my opinion depending on circumstances
