Manuka honey is brilliant - has the active manuka facotrs which come in +5, +10, +12, +15, +20 and +25
I would recommend the +10 as that is a good start, and I have stuck with that for years. I only take it occasionally now.
As for Sidr, though I do not know the mind of the Prophet pbuh - I think it would makes sense given what we know about local honey being beneficial that the Prophet pbuh advised the Arabs to eat Sidr honey which is from Yemen.
In the Muslim world, the honey producing countries are Morocco, Yemen, the United Arab Emirates and Jordan.... Yemen would be the most local for those who live in Makkah or Medina.
So again - for the Arabs, Sidr was local honey.
Allahu alam.

EDIT: honey is mentioned in the Qur'an as having benefits for the human being. The Qur'an doesn't mention where that honey has to be from, and if we use our common sense we can know that honey is local to every place on earth where there are bees. So, Allah in HIS infinite mercy ordained for bees to make honey all over the world for our benefit.
Local honey carries the correct properties to fight off local allergies. If one was to eat a honey from a place faaaar away, while they were in their own locality, the honey would not be as effective. The reason for this is because the pollen the local honey bees use fights off the local allergies, and so if you use a honey from a far off pace it won't contain the same properties as the local one and would only really be suited to the locality it came from.
Having said that - Manuka honey comes from New Zealand, which is kinda far away - yet it has healing properties of an altogether different nature. IN the case of manuka honey it is especially beneficial for internal problems and burns etc.
