5130P DOES NOT have a PREMIUM over 5110P.
The only reason there is a different in price is because Patek increases their list price year on year (most years), and when they launched the 5130P after discontinuing the 5110P, the price increased, in line with the rest of the models.
If you think carefully, what you are saying is exactly why a 5167 has a premium over a 5065, however, the only reason a 5167 list price compared to the list 5065 is because they belong to a totally different production yea! A datograph this year also definately cost more than one bought 5 years ag! Logic!
Anyway, i'd say both watches are brilliant, the datograph is big and chucky, looks robust! I feel thedato oozes the feeling of a very very solid, buff, attentntion seeker (no offence). I would associate it to what someone who bench press100pound weights, i.e ARNOLD SCHWARZENEGGER!
The patek, well.. it's a totally different ball game, it reeks of smooth, gentleman class, charm, something which like how suave james bond, less his destructive behaviour!
Well, i chose the 5110P, it'spractical, discreet but most importantly, it speaks to me! But both watches are really amazing, you should find a way to try both on before deciding.
