Are Burmese cats good apartment pets?

I've read mixed things regarding burmillas as an indoor cat. Seems about 50/50. I have a burmilla who is an apartment cat - as I'd read they were good indoor cats - and I'd say he is quite high energy and you need a good amount of space still. He has a tall scratch post and a LOT of toys. We also trained him to be on a lead and he will go for 'walks' which he LOVES. He will sit by the front door crying and purrs as soon as he sees his lead. He goes in the car too. I do feel bad sometimes as I think he would really love to be outdoors more. I think possibly it depends on the individual cats temperment.
