Advice on Egypt visa on arrival versus e-visa for UK citizens

Hi everyone, I am currently planning a trip to Egypt from the UK for next month and am trying to figure out the best entry method. I see that UK citizens are eligible for both the strict Visa on Arrival and the multi-entry E-Visa. I have read conflicting reports that the online portal can be glitchy with photo uploads and payment processing. Has anyone traveled recently from London to Cairo? Is it generally safer/faster to just bring cash for the airport sticker, or is it worth the hassle to try and secure the electronic one beforehand?
