JLC Master Chronograph or Zenith Class T El Primero Chronograph: Which One's Best?

[Datejust10019]

The first three images are of a circa 2001 Zenith Class T El Primero Triple Date Moonphase Chronograph in 18K rose gold on a black alligator Zenith strap fitted with an 18K rose gold butterfly deployant.

The fourth image is a circa 2011 Jaeger LeCoultre Master Chronograph in 18K rose gold on a dark brown JLC alligator strap fitted with an 18K rose gold butterfly deployant.

I have been looking for a watch with a chronograph and moonphase complication; the Zenith's complete calendar complication, however, seems like an added bonus. I was able to find only one such Zenith watch available on the domestic and international markets, so perhaps this reference is scarce or rare.

The JLC Master Chronograph is quite an exquisite piece. Stunning really.

I've tried on both watches and they each have their distinctive merits: Zenith's famed El Primero movement, multiple complications, dial detail; and JLC's equally attractive design features, stellar quality and reputation.

I'm debating which one of the two to add to my collection to mark and celebrate both a wedding anniversary and graduating from Harvard with a master's this year.

Thoughts?
