The Stealth is classic. An icon. But I am a bit biased against the Stealth only because years ago I spent a lot of time comparing it to the 101.027x (silver dial, printed markers, and blue hands in a WG case), which I liked much more. As a result, it's hard to me to look at the Stealth and not think about that. I prefer the older movements (101.025), too.
The PT L1 Moonphase (192.025) has a nice, balanced look to it, but I never liked the lume plots -- the twelve plots around the time subdial and the plots for the power reserve indicator.
The "negatives" (for me) that I raised are really minor. We can all find small "faults" with most of our watches, including the ones that we own. Overall, I like both of your potential choices and feel like you can't go wrong with either one. There's a reason these are popular models!
But if you're looking to buy a brand new 192.025, can you still get it? I thought it was discontinued, unless you found one still in stock.
