Which is better for DIY coaxial cable F-connectors: screw-on, or crimp-on?
Neither. Compression connector for the win.
Cable guys have transitioned to compression connectors because they are wayyyy easier and faster. Crimp connectors, for all the betterness they were 20 years ago vs. available options at the time, pale in the convenience of compression connectors. I bit the bullet a couple years back and got a plier/stripper kit along with a package of ends. It only took one use for all my crimp connectors and (very high dollar) crimping tool to go straight to storage. Strip the wire, stick the connector and wire in the tool, and squeeze. Done. Takes mere seconds and there is no twisting, cussing, cramping fingers, or stabbing yourself in the hand.
However...
If you just need one or two cables a year and they will be light-duty and indoors, go with screw-on. If you don't need custom sizes and can wait a couple days, order from AmazonBasics.
