Porting in / parking 10 + numbers - should I use Fongo FPL?

Newbie, tired of paying the big 3 phone companies monthly fees to park my numbers.
I'm looking to port in 10+ numbers and park them for a longer period.
I am confused on the difference between Fongo and FPL.
I downloaded the app and FPL PC app.
I wouldn't need to make calls or use the numbers at all simply park them. (if the option was there would be okay but not necessary)
Can either handle multiple numbers at one time? Under 1 account?
Are both $25 to port in and free to port out? I read somewhere in the forums that Fongo is $20 to port in but also said $25 to port out.
Do both take the same amount of time to port out if needed in the future.
thanks
