Renko or range bars for scalping: are they really cleaner than time candles?

Both build bars from price movement instead of the clock. A range bar closes once price has traveled a fixed distance from its low to its high. A Renko brick forms only when price moves a set amount beyond the previous brick's close, and it ignores everything smaller. The appeal is obvious: quiet stretches produce nothing, fast stretches produce a lot, and the chart looks tidy.
The comparison with time candles shows trade-offs.
Time candles keep the clock. Every minute gets a bar, so session behavior, news timing and spreads at specific times line up. Noise appears as small overlapping bars in dead periods, which can generate false signals, but nothing is hidden.
Range bars filter chop and make breakouts obvious, yet they do not tell you when things happened. A burst of ten bars can come from ten seconds of news or ten minutes of grinding. Renko goes further by discarding intrabrick movement, so a spike that reversed inside a brick leaves no trace. That is a problem for stop placement, since the real path was wilder than the bricks suggest.
There is also a testing issue. Many platforms build these bars from lower-resolution data, and the result can repaint or differ between vendors depending on how reversals are handled. A Renko chart with the same brick size can look different from one platform to the next.
A reasonable use is as a filter or a visual aid, with entries and exits still managed against real price and real time. Treating the bars as the market itself is where trouble starts.
Which one has worked for you in practice, and do you still keep a time chart open beside it?
