Yeah it really depends on the honey.
Some strong honeys will bring an overpowering flavour (in addition to sweetness) that makes it become 'honey tea' as opposed to sweet tea.
Other honey will be more mild.
I usually put an equal amount of honey to sugar, but sometimes I put more in, if I am going for an Indian style sweet chai.
On another note, stay away from commercial 'supermarket' style honey. They are over heated, have lost most of their nutrients, have lousy flavour and sometimes have had other sweeteners added. Also some of the honey is from questionable sources with concerning bee keeping practices.
Another thing to keep in mind is the temperature of the honey. Both Ayurveda and Traditional Chinese medicine recognise that heated honey can be toxic, and recommend if using honey, it should be raw honey, and you should wait for your tea to cool down a bit before adding it.
I really only add honey to black teas with milk, herbal teas, and sometimes when I am feeling crazy, a milky sweet puerh tea I sometimes make.
