Your choice of tools always depends on the use case. If you're only going to be creating these archives for internal use, or will be exchanging them/reading them on modern Unix-like systems, then there is no worry about the decompressor not supporting LZMA. If you need to exchange files with feature-poor systems, then yes - stick to the de-facto standard. Besides, what "better" archiving format are you going to use? Tar clearly isn't one (the great... grandparent comment wouldn't be asking for alternatives if it were). "Defacto standard" ZIP files have a poor compression ratio. 7z feels strange to use in a professional setting or for long-term storage. RAR is a closed-source abomination. Are there any other "better" archiving formats that have wider (de)compressor adoption than ZIP+LZMA?
