Default to 「絶え間なく」 for something continuing without a pause, as in 「絶え間なく雨が降る」. In written prose 「絶えず」 is the usual pick, and 「延々と」 suits things that drag on endlessly. The others are narrower: tears (「止めどなく」), visitors (「引きも切らず」), no limit (「際限なく」), colloquial nonstop (「のべつ」「のべつ幕なし」「ぶっ続け」), formal 「間断なく」; for the opposite, stop-and-go sense, use 「途切れ途切れ」 or 「断続的」.
