7z archives most commonly use LZMA2 since it's the default option when you select 7z container in 7Zip creation window.

Zip files most commonly use deflate for their compression, although you can use any algo with a zip container (zip header is PK). For example, Crysis 2 Remastered uses LZ4 on its zip game archives. We Are Football uses ZSTD on its zip archive.

Afair there's no current easy precompressor (e.g. xtool) for lzma[2]. I know pLZMA exists on encode forum but it's not a precompressor like XTool.
