tar is usually smart enough to figure that .tar.gz is a compressed archive, so tar xvf suffices.
Moreover, .tar.xz archives are much more common nowadays, and the flag to tell tar to use xz decompression is J. Yes, uppercase J I shit you not, because all other letters of alphabet were already taken. The next commandline option added to tar is going to be a Unicode emoji symbol.
i always forgot about -J so i got used to writing tar --xz -cvf archive.tar.xz file1 file2… instead. it’s a bit more explicit and i’ll never have to hunt for the same flag in the man page again.

Burrows–Wheeler algorithm or block-compression algorithm, the bzip2 file compression program was developed by Julian Seward.
Ah yes, totally makes sense.
XZ Utils started as a Unix port of Igor Pavlov’s LZMA (Lempel–Ziv–Markov) algorithm, by Lasse Collin, and then by the Tukaani Project.
So apparently the uppercase
Jstands for “that guy who made a better compression algorithm than Julian”.
