Are new Briggs engines any good?

After a long and ugly battle with Home Depot, I ended up trading my 3-y/o Powermate 5kW/6.25kW generator with it's Subaru EX30 engine for a B&S 5.5kW/8.25kW generator. The Briggs is powered by a 1450-series engine (14.5 ft-lbs).

I really liked the Subaru engine, and hated to dump it, but the case seal was bad and the HD contractors were too incompetent to fix it. The motor weeped a bit of oil from the bad seal, but was maintained and tuned exquisitely (by me) and ran like a Swiss watch. I would've done it myself, but it was still under engine warranty - unfortunately, the small-engine shop HD uses are a bunch of blithering boobs. HD ultimately offered to take my generator back and give me a new one. The closest thing they had was the B&S (Storm Responder).

I'm really not a big fan of B&S motors in general, at least not the new ones (especially compared to something like the Subaru EX30). As an emergency piece of equipment, this thing needs to run good and be reliable / trouble-free. Should I be worried, or are these engines OK?
