Can I get some purchasing advice? What features are important?

Hi guys,I'm interested in the smaller DJI drones, but I could possibly make do with the Ryze Tello, which apparently uses some DJI components. I mainly want to use it for casual aerial videography, "selfies", exploring the nearby areas of the local woodland (and I am happy to walk closer the areas I want to explore before launching the drone).I have compiled a comparison list of the three models I am interested in, but I am wondering if there are any important drone features that I am unaware of, that should be added to the comparison. NameRyze Tello + controllerDJI Mavic MiniDJI Mavic Air 2Price (US)140$400$800$Mass80 g249 g570 gSpeed8 m/s13 m/s19 m/sRange100 m4,000 m10,000 mBattery13 min30 min34 minGPS/GLONASSNoYesYes3-Axis gimbalNoYesYesSD-Card slotNo256 GB256 GBPhoto5 MP12 MP48 MPVideo720p1530p2160p via /r/drones https://ift.tt/3oxmsBb
