Morituri is currently the best secure/accurate ripper available, if you're concerned about getting perfect rips, then it's the one to use.
AUR package: https://aur.archlinux.org/packages/morituri-git/
It's worth noting the what.cd recommendations, I think you would be hard pressed to find a more anal group on the subject of accurate CD rips. Essentially, Exact Audio Copy is the de facto standard and can be used in Windows or Linux (with Wine). Other good options appear to be XLD for OS X and morituri for Linux.
There are 2 main steps to the process ( though some programs like to hide that from the user). First is actually ripping the CD - getting a good error free read to extract a perfect WAV, then secondly encoding and tagging whatever formats you require.
Current favorite for Linux rippers is Morituri which was the first on Linux to include support for the AccurateRip database. You might also look at RubyRipper, or anything else that uses cdparanoia
Point the ripper of your choice to the flac encoder which should be available in the repos for your distro, or grab the source from http://xiph.org/flac/download.html
Disk space is cheap (especially compared to the time it takes to rip) so rip to FLAC as the most compatible lossless format, and then you can easily transcode to any other format in just a few keystrokes / clicks. This way your Music collection is future-proof (so long as you back it up), and you can easily use the most suitable / appropriate lossy codecs to save space on portable devices.
I did something similar using Morituri (https://github.com/thomasvs/morituri). It accesses an online database of disc fingerprints and gets all the metadata. It worked perfectly for most of the discs I put in. Some I had to find the metadata myself.
