Amazingly, I own pipes on both sides of this comparison, a Peterson 999 Killarney P-Lip and a Savinelli Opera 673KS. The comparison is handicapped only by the Pete being a P-Lip, my only P-Lip, and perhaps by the Sav Opera being a somewhat up-market version of the 673, with the extra size of a KS and the series being also somewhat up-market. I find them both sturdy and competent pipes, hefty in hand, but not overweight in any way, and beautifully balanced. I have had no complaints with any of my Petes, and this one is no exception. However, the 673KS has the look, feel, and draw of a luxury pipe. It compares favorably to the best in my stable, a Ser Jacopo and a Ferndown. It's just noticeably more of a pipe. Take the specifics of these pipes into consideration; they aren't a perfect match. But from these, liking them both, I'd recommend the Sav.
