Just wondering what's the difference between the two types:

I have a twin lead cable coming from an old antenna. The antenna is very high and out of reach. I replaced the other end with a Push-On Balun. I wonder if I would do better if I replace the Push-On with the other type at the same location.

they are both bauns
the eagle device is designed to go onto a jack, like the antenna input of a CECB or a VCR
the magnavox device is designed to go onto an antenna or the 300 ohm antenna input screws of a tv for two uses
if you put the magnavox device on the antenna terminals (on the antenna) then you can use coax cable all the way from the antenna. usually this is easier than running twin lead because the twin lead has to be installed properly to make it not loose signal. you stated the antenna was out or reach so this may not be your preferred solution.
you could put either on the end of your current twin lead. you could using some method (like a pair of nut and bolts covered with tape) attach the magnavox device and have a much better connection than the push on.

Use the magnavox at the antenna and get rid or the twin flat lead...
Use the eagle to connect the twin flat lead to the TV's 75ohm input connector...
Apart from that they are both baluns and accomplish the same thing...

One difference might be that the push-on one might have been engineered for attaching an FM dipole to a 75 omb F-71 jack, and might not have the frequency response you need for UHF TV reception. I found one such jack that became a veritable brick-wall filter above 500 MHz and had to replace it.
I personally would never consider a "push on" coax connector.
IMO, it's good for "emergency" use, but not as a permanent solution. Use a screw-on F connector.
the push-on type is only meant for indoor use....outdoors it will be damaged by rain....
also, unless its marked VHF/UHF, it may only pass low vhf signals....
