lumia 1520
pros
+latest specs (faster and most likely is upgradable to wp8.1)
+beautiful screen
+expandable storage
cons
-camera (image/video quality performs not as good as expected during low light/indoor. some say it is a fixable issue but since it is a 'hardware limitation', we can only hope for miracles)
-6 inch size (one hand operational is almost impossible.. unless u're a titan XP)
lumia 1020
pro
+camera (that 41mp speaks volume)
cons
-one year old specs
-no microsd slot (have to content with 25++gb but can relieve the storage burden with skydrive)
i was in the same dilemma as u r now but i've decided to wait for the next nokrosoft flagship instead because those 2 beasts of a phone above doesnt really convinced me to break the bank yet.
why not wait for 1 more week to see what nokcrosoft is going to unveil in the CES on 7 jan 2014? unless, u really need to buy the phone right now, i'd say go for the lumia 1520. only because it's the latest high-end lumia and upgradable to wp.8.1.

Agreed.
If you can't wait, you can grab Nokia Lumia 1520. New model but the size is so big.
Handling with one hand is almost impossible.
To me the the best size for the phone is 5.0 - 5.7inch with 1080p screen.
Galaxy S4 and Note 3 are the best examples
