I prefer Flightradar24, it is much quicker to come up.
If a family member is traveling , flightaware works really well for following a flight. When at home, if I hear something unusual, flightradar24 comes on for the airspace around my house, and I can identify them quickly.
One that has been pretty busy lately is the Florida Highway Patrol. The have a Skyhawk that does speed enforcement north of my house, generally for 2-3 hours starting at 7am, on I95 northbound. They generally do not do southbound because there is a restriction of PBI airspace.
