If the toro has the super flow system deck then it's a great mower, otherwise they are both junk mowers. They will give you an adequate cut for weekly lawns and slow growing lawns but won't cut wet or thick lawns.
It might be what you need, it the troy-bilt is fairly new then it could last you another two seasons for you to upgrade in the future.
There is an Old Blue Chair for each and every one of us, we just have to find it.
