angled are easy to get on with a bit of effort. Then you get used to them.
After that the multitude of options of how to use them, including laying on your back looking up into the eyepiece is flat beyond amazing.
I have a straight eyepiece Zeiss though, because it was a good deal, but if I had my choices, they'd all be angled forever more.
Caveat we started angled in competition, and hence we have tons of hours behind them so they may be easier for us to use than for others to get used to, though we'd never used an angled one before we bought our two Kowa, and in the first match we used them at Carolyn and I never had an issue finding our targets or viewing them.
