Hi Canuck88,
Well, it sounds like you may already answered your own question. If you like the light weight of the Toro you will not like the tank like feel of the Exmark.
I had fun and was extremely impressed with it for the 25 minutes it took to finish the yard after my wife had enough wrestling it around.
I知 of a lighter frame and work indoors as an avionics technician. Depending on your physical condition, amount of space you need to cover and cash you have to spend, your answer is in there somewhere. If you are fortunate as I was, try to find a shop that will let you try before you buy, or at least one that carries both models. If you find the Exmark a little too much mower at least you can exchange and although you will get a refund , the shop doesn稚 lose the sale.
Hope that helps.
Brian
Thanks Brian - I'm a pretty fit, active guy in my mid-30s, and our yard is about 0.25ac... I think the best thing is to just try the eXmark out...
