I don't know B&S, but if its the right size with the right hp to do the job then I don't think you can go wrong.
As much as I love Yamaha I don't think your use profile pushes you there.
There are other machines that will do that as well, what you want is what works for you price wise, mission needs. I see nothing wrong with your choice.
