Naturally Artist is correct: get both and try out for yourself.
If you want only one of them go for Il-2 1946 patched to 4.12.1
You can fly on three continents, take part in allmost in all the major battles of WWII in dozens of different aircraft. If you intend to fly offline, there is nothing like Il-2 1946. Thanks to the community you can download hundreds of excellent missions and dozens of exiting campaings for free.
No way to get more value for your money
