I suppose that depends on the comparison. In Europe, Pedersoli is widely seen as the higher end of production Italian replicas. If comparing to Traditions or CVA, I'd definitely prefer a Pedersoli.
When I wanted a production, but reasonably authentic plains rifle, I first opted for a Lyman Great Plains rifle (now out of production). I have that back home in Texas. In Europe, Pedersoli sells a Rocky Mountain plains rifle that is ~$300 more expensive, but has much nicer wood, a traditional lock, a German silver front sight, and overall, the fit and finish is much better than the LGP. I bought that in 2022. That will likely be my last production gun.
If your budget is $1000 and you can get the Pedersoli kit for under $1000, that's probably your best bet.
However, if I were going to finish a gun myself, with nicer wood, and some other upgrades, upgrading the lock would be high on my list. I have one L&R flintlock on a TVM Southern Rifle, and it is certainly better than the other production Italian replica locks. Function before aesthetics, I'd probably upgrade the lock before upgrading the wood.
If I were building a kit, I'd start with a Kibler, even if that meant waiting a few months to expand my budget to $1300 or $1500. If I thought I needed something less expensive for a first foray into building, I'd start with a production pistol kit.
