On first glance - the 6119 looks very much like the 2013 Vacheron Constantin Traditionelle Small Seconds, but adds a nice hobnail bezel. I have been eyeing some of these in the past in a grey variant, so to see it similarly configured in PP is interesting. The VC comes slightly thinner but all in all pretty similar in terms of movement specifications. Hence - I think this a meaningful incremental improvement to the 3919 and 5119 and way better looking, but compared to the VC is similar. But it's a PP!!!
As for the 5236P - love the new movement layout and the continuation of a micro rotor (although would have still loved a gold hued rotor). Also a huge fan of the placement of the seconds hand - prefer this over the 5320. Also the "single line" calendar is pretty innovative and probably extraordinarily difficult to execute (it makes sense), I guess I am so used to the old school two window version of day and month, as this is Patek anything that is too different vs historical models is considered revolutionary - and I have a little allergic reaction. Would have loved to see some kind of use of the dial real estate on the right and left of the dial - maybe for a future perpetual calendar chronograph, with an automatic micro rotor? (Mind would be blown then!)
Both are classic, eternal, elegant pieces which no doubt will look great in 100 years. It's innovation Patek style and compared to Rolex and AP, certainly a very deliberate approach that will be successful.
