It's a company that makes a lot of the props FliteTest includes with their power packs.

I think that's the style of having flat instead of tapered or rounded tips on the propeller blades.

Umm, it looks different...? Maybe someone else who understands props more can explain the pros/cons. If there wasn't an advantage to bullnose, I doubt companies would make that kind of prop.
Bullnose props produce more thrust than regulars. The increase thrust comes with much higher drag, resulting in bullnose props being less efficient. Bullnose props work in situations where you can not use a larger prop. Situation like on a quad, you can’t use a 6 inch prop on a 5 inch quad. The props will hit each other.

It will work if the prop fits, some DJI props are self tighten, they don't fit on every motor, but props with a standard mounting hole should fit, maybe spacers are required.

Wake up! Time to fly!
I love Gemfan
Gemfan are teh EBIL of props. You look at them at the wrong angle and they shatter. HQ isnt too bad. I run Dal Cyclones on everything I fly quad wise. they have a super consistent power across the entire throttle range. Slightly heavier but with motor tech these days thats a non issue. HQ and Gemfan do not they have sweet spots which is why some pilots love them and they fly smooth and others cant tune em for crap with mid throttle oscillations due to their rates and flying styles.
Master Air screw and APC are top of the line fixed wing props so I dont know much about those. Yet.

Gemfan APC props are okay and do the job, I dont spend a lot on props for my foam planes.

Forgot to properly tighten an 11x7 Master Airscrew three-blade when bench testing it. The prop released at around 1/2 - 2/3 throttle, flew across the room (I was testing it in a lateral position rather than facing up, which is good as it could have taken out a lightbulb or something had it take off upwards) hit the wall then cartwheeled off sideways... It barely even chipped. I Don't think I could find a mark on it now.
A 9" three-blade not made by master airscrew faced the same challenge recently (I tightened it as much as I could, it just couldn't get sufficient grip on the motor shaft) snapped a blade off.
