What's the problem with AirMap.io? I have it and it looks similar to other restricted area maps, at least in the areas I'm familiar with.
I usually use AltitudeAngel.com because it gives you phone numbers for the all (or almost all?) airports. I've used this to let the controller at small local airports know that I will be flying the camera UAS in a certain area (within their 5-mile radius) below a certain altitude (400') and at a certain time. So far, that has worked out OK.
