Leman GMT has an automatic winding alarm mechanism
Leman GMT alarm and Compressor Geo are 2 watches I've been looking for as well. I've found that the Blancpain Leman GMT Alarm has an automatic alarm movement, indication of the reserve power of the alarm mechanism and on/off of the alarm.
Very interresting as well with the 1241 calibre is the alarm and date are indexed/synchronized with the second time zone, very useful in my point of view. (I don't know if the 2 others JLC have those features).
Because the alarm movement is automatic (not manual winding), you won't need to wind it, thus, no excuse to miss a rendez-vous (because you didn't wake up) 
Cheers,
Pascal

Tough choice...
Blankpairn Leman GMT Alarm, JLC Extreme World W-Alarm or JLC Master Compressor Geographic? In a week I will go for a short shopping trip and one of these watches will follow me as my travel companion on the planes. I will buy a SS watch with SS bracelet. ...
MC Géographic, Dr Kol
As you already have several Alarms. So, thr MC Géo will bring to you a bit of diversification. But you forgot one... The Extrem World Chrono! Best, Nicolas
If.....
the Extreme World Alarm fits your wrist then I would vote for that But all choices are sound ones Cheers
Good advice above
Both Nicolas and PinkPanther give good advice above. Between the BP ad EWA, I would go for the EWA, without question. The EWC is an awesome travel companion -- I happliy take mine everywhere. The fast strap change is great for changing the watch for diffe...
similar experience
I went through a very similar experience about 18 months ago. I actually purchased the Blancpain GMT alarm and liked the alarm gauge and separate alarm clock. BUT I could not easily read the GMT hand without having to really focus on it, and I am only 25 ...
That's true that the Alarm of the MC Memo is
A bit louder than the one on the new models: EWA, Polaris and Navy Seals Alarm. Thanks, Matt, for this precision. Best, Nicolas
Also depending on what you've got allready
My choice between these watches would be the Blancpain. But I guess on the JLC forum you get many votes for the MC pieces. Put them on your wrist a few times and go for what suits you best. Both are fine brands with great history. Assuming quality is alik...
one more difference!
The JLC models that you are looking at DO NOT have display backs although the crests are very nice. The Blancpain DOES have a display back so you can see the rotor and movement when you are not wearing the watch!
MC Geographic Back
The JLC MC Geo might not have a display back, but the rose gold inlay makes up for it....
i respectively disasgree
the caseback on the MC series is nice but not more pleasing than an exposed 'alive' movement.
