For me, it has to be time. The reason is that it is a consistent cadence, and I trade markets without volume. And, my original exposure to the markets was thru Gann analysis, to which I happened to be well suited. If one has access to volume, it is no contest. Volume charts give a true picture of what traders are out there doing. I use time charts that require a multiple layering of range and volatility. Volume charts can be traded nearly without any indicators. Just support and resistance. I however am ambitious and refused to accept that I could not trade the largest and most liquid market on earth. Regrettably, there is no volume. But that's okay, for there is always another way.
Don't underestimate who may gain knowledge/understanding from your unique perspective on how you see the market.
