i personally use "freerip"... mainly because i've used it for about 10 years and it's been continually updated.. The free version is a little crippled (only 1 thread encoding so a cd's worth of files takes some time.) but I have a paid licence for it that opens up all the options and encodes faster. so ripping like 30 files with 8 cores takes like 20 seconds. i think it was only 20 bucks.
some are better than others... just try a bunch out. an mp3 encoded with a set of settings in one program is the same as an mp3 encoded with the same settings on another program.
there is piles of open source rippers out there. so you could also get something like "freac" and see if it works to your liking.
