• Synonym遅々ちちWrittenWritten/formal prose for slow progress, typically 「遅々として進まない」; can also describe slow steps. For spoken slow-going, のろのろ is the usual choice.
• SynonymぐずぐずCasualDawdling and indecision — dragging things out without deciding, as in 「ぐずぐずするな」; also complaining or unsettled weather. Broader in range than のろのろ.
• SynonymだらだらCasualDragging on endlessly, at tedious length, as in 「だらだら話す」; also liquid trickling down or a long gentle slope. のろのろ is about slow speed itself.
• SynonymゆっくりNeutralNeutral slowness — unhurried and relaxed, no negative tinge; also ample time or resting well. のろのろ carries a frustrating, critical nuance.
• SynonymのそのそCasualLumbering, heavy movement of living things, as in 「のそのそ歩く」; mostly animals or people. のろのろ also covers vehicles and slow progress.
• SynonymのそりCasualUsually 「のそりと」: a living thing slowly, dully making a single move, as in 「のそりと起き上がる」; the focus is on one action.
• SynonymのっそりCasualDull, lumbering movements of living things; also standing blankly still, as in 「のっそり現れる」. のろのろ stresses slow speed and dragging progress.
• SynonymもたもたCasualFumbling, dawdling at a task, as in 「もたもたしている」; the point is things not getting done smoothly. のろのろ is about slow speed itself.
• SynonymもっそりCasualRare word: advancing slowly, in fits and starts; also describes a person as rustic and dull. For everyday 'slow', のろのろ or ゆっくり is normal.
• AntonymさっさとCasualAntonym: getting things done briskly, without hesitation or delay, as in 「さっさと帰る」; the opposite of the slow, dragging のろのろ.

Use 「のろのろ」 for movement or progress so slow it frustrates, as in 「のろのろ運転」. For neutral, unhurried slowness say 「ゆっくり」; for dawdling, 「もたもた」 or 「ぐずぐず」; in written prose, slow progress is 「遅々」. The rest describe lumbering movement (のそのそ・のそり・のっそり・もっそり), endless dragging (だらだら), or the opposite, brisk action (さっさと).
