00Buck,
I have not seen the 2.5-20x50 but have experience with the 2.5-10x42 Compact.
Firstly, there is nothing compact about the largest NF 'Compact'. On an AR it is a decent scope which takes up all the space on the rail. It is proportional however for an accurized AR, without getting too silly. Because of that I'd say there there's not a lot different between the two scopes, except that one is twice the magnification than the other. The 10x is 580gm, while the 20x is 810gm. That is not a lot of extra weight for twice the magnification at the same length, 12". As for weight, the difference in weigh between the scopes is 200gm. On a 10lb (4,500gm) gun that is not a lot of difference.
The difference will be the price, and the objective is bigger. More objective means more light for the same magnification but in typical hunting magnifications 4-7x you won't notice the difference. When scoping bullet holes on targets and wanting to see detail, you will notice a difference.
As for focal plane, unless you need to judge distance to target while under pressure, like in the military, then SFP will be perfectly fine. With a Mils graduated reticle you can dial up a SFP to the magnification it's set in the factory and still judge distance. At the Range you'll know the distance and a lot of shooters now carry compact laser range finders.
