I've shot the SBE2. My cousin has one and has put 6000-8000 basically trouble free rounds. Great gun. BUT.. I have shouldered the new A5 and man does it feel sweet!! And it's a quality made Browning. So I don't think you could go wrong with either.. Buy one or the other and have many years of happy shooting!!
If I ask a question, I don't want your opinion. I want facts.
Don't tell me something you think, tell me something you know.
It's easier to say I don't know, than make something up.
Although, being a forum the next guy will know more no matter what.
