I think that the more you'll wear them, the more you'll find a ranking of the watches you like best.
But your certainly have now a very interesting collection and I guess some of them may disappear for a while but be back again when you feel like wearing them again.
It doesn't matter when a watch stays a little bit in the safe if it comes back for a long wrist time after a while.
Yes, the complications, and chronographs in particular as they are a complication Patek masters greatly, are a new field to explore, but I guess it will come naturally when you'll feel like it.
I saw it recently and I must say I don't see what I don't like inthis 5370P.
The enamel dial is beautiful of course but I didn't pay that much attention to the side case from the pictures we could see and I can tell it looks great.
If you consider a chronograph from Patek Philippe, with many interesting technical improvement since the in-house caliber, this one is maybe my favorite.
