What each one is
asdf
asdf is a command-line tool that lets you install and switch between different versions of programming languages and runtimes on a per-project basis. You add support for each language by installing a plugin. The README says it works like tools such as nvm, rbenv and pyenv, but in one tool with one set of commands.
Oh My Posh
Oh My Posh is a program that draws the prompt line in your terminal, the text you see before you type a command. It works across several shells and operating systems, and you control what appears through a theme configuration. The README describes it as a prompt theme engine that is shell and platform agnostic, with support for secondary, right, and transient prompts.
Best for
asdf

Strengths
asdf
- One command set covers multiple languages through plugins
- Reads existing files such as .nvmrc and .ruby-version, which eases migration
- Supports shell completion for Bash, Zsh, Fish and Elvish
Oh My Posh
- The README describes it as cross platform and shell agnostic
- It lists configurability as a core feature and points to online documentation at ohmyposh.dev
- It is MIT licensed and has an active release history shown in the metadata
Not ideal for
asdf
- People who only use one language and one version, since a single-language version manager may be simpler
- Users who need a graphical interface, because the README describes a CLI tool only
Oh My Posh
- People who are happy with their default shell prompt and do not want to edit configuration files, since the README indicates setup is configuration-driven
- Users who need a full shell replacement rather than a prompt tool, since the README describes only prompt rendering
Trade-offs
asdf
- Each language depends on its own plugin, so support quality varies by plugin (inferred from the plugin model described)
- The README is short and points to external docs for setup details, so the entry relies on those docs
Oh My Posh
- The README is truncated and does not show install steps, so setup details must come from the documentation site
- Heavy customization can add configuration effort for newcomers
