"The software is clunky" Use Nova Launcher, my favorite for years! Add it as the default and it will start up after rebooting instead of the Asus UI.
"It has capacitive buttons" That's definitely a plus for me! I hate seeing software buttons instead and the auto-hide and seek that goes along with it. Of course Samsung's latest phone seems to be all screen because the capacitive buttons are now software and that area is STILL only limited for those button functions while adding a strange screen aspect ratio.
"The processor and ram aren't fast or enough" Not sure WHAT other people do with their phones but I love photography, videos, browsing, email and use my phone all day long, haven't noticed anything going slow.
This phone is an excellent purchase, got it a few days ago, it's all set up and I love every aspect of it with Nova Launcher and a fast Sandisk micro sd card for the 4k video.
