If my tables are right, 2.5 mm is about 10 gauge, which is a lot more

It is called 2.5mm, but it is actually 2.5 square mm, which is about

Well you still have the doubled advantage of feeding the ring from both ends
and using twice the voltage.

I'm not so sure about rings, but the doubled voltage looks good to me given
that I would have enough appliances that ran on 240 volts to be interesting.
I don't.
