It's better than it used to be. It might still require some basic cli skills. Especially formatting disks and mount points. And file system types. Etc.
Easy or not depends vary wildly. But the usual task is
partition the drive
format the drive
mount the drive
install the base system
That is the bare minimum, but we need to do more configuration to be able to boot. Hence the next task is configuring the following
fstab
timezone, hostname, and networking
boot loader (I just use the EFI directly nowadays)
That is it. Everything else is usually work specific. Like, if you wanted arch to be a server, you usually didn't install a GUI. For workstation and gaming, you need more steps but it will vary depending on hardware. The archwiki covers a good deal of hardware from laptop to desktop and their quirks.
It'll depend a lot on your experience. I can just install Arch without reading the wiki at all in about 5 minutes for something fairly vanilla. If you're comfortable with Linux then following the wiki won't be too hard, took me maybe 2-3 hours on my first install before I had my DE and everything all set up (12 years ago). If you've never used Linux before and take the deep dive then it could take hours and days depending on how fast you can absorb all that information.
"Easy" is very subjective, there's stuff that's so dumbed down for the sake of "easy" that it makes my life harder when I need to do more complex stuff. I know people for whom linear algebra in 11 dimensions is easy for them to do and solve. Easy is relative to your own personal experience level and what you're trying to accomplish.
Install it in a VM as a test run, you'll see by yourself.
