I prefer the Pietta 1851 Navy .36 "type" revolvers over the Uberti revolvers because I have an affliction known as "parts-changer-syndrome", which is very contagious if one decides to start creating Confederate revolvers using parts from VTI and Taylor's. Only two Confederate 1851 Navy "copy" revolvers were brass frame: the Schneider & Glassick and the Griswold & Gunnison, both in .36. The rest were steel frame: Leech & Rigdon, Rigdon & Ansley, Augusta Machine Works, Columbus Fire Arms Manufacturing Company, J.H Dance & Brothers, L.E. Tucker & Sons, and George Todd.
Both Uberti and Pietta have used CNC machining since ~2002, so parts from either manufacturer are pretty much a "drop-in" fit within the respective brands since then. Some folks dislike the Pietta "billboards" on the barrel; Uberti is much more discreet. Uberti's are more expensive than Pietta's. IMO, Pietta is better mechanically (arbor fit, internals, et al).
If you do get into parts changing with the Pietta CNC 1851 Navies, be advised that there are two different 3-piece grip assemblies (trigger guard, backstrap, and wood). The first, manufactured ~2002/BS - 2014/CM, is known as the Large Tail grip. The second, manufactured 2015/CN - 2020/CZ, is known as the Non Tail grip. (The gripframe assembly manufactured prior to the CNC guns is known as the Small Tail grip.)
If you are interested, I have studied this for a few years and created a thread about them here:

NorthFork, I you get to the affliction stage that I have, all it takes is money. My L&R started out as a Pietta 1851 Navy steel (CP/2016) and I substituted the Pietta G&G .36 part round/part octagon barrel and smooth/plain/non-engraved cylinder. All off-the-shelf Pietta parts from VTI. I also found some wood with figure on Ebay to replace the plain quarter-sawn straight-grained factory wood. This is probably the easiest parts-changer revolver to create: plug-'n-play, to borrow an old Microsoft adage.
I agree with everything posted here prior to my post. It just depends upon your preferences and the route you wish to take.
If you want a shooter and like smoke and report, stay away from brass frames.
