I think viewers like gitk or tig, or more powerful tools like magit/sourcetree/etc. when used purely to see your repo's history, are not only acceptable but are the quickest and most intuitive way of understanding what's going on. I'd hate to be restricted to `git show --oneline --abbrev-commit` or similar commands that don't show branches and merges.
