Who charges faster: Supercapacitor or Capacitor??
Do you have any article that tells the value in seconds in charging the supercapacitor or capacitor???
Aside from that, do you know any major differences between them besides the capacitance value??
You can check these articles;

(Nano Energy 52 (2018) 441–473).2- doi:10.1016/j.jpowsour.2006.02.065. (Journal of Power Sources 157 (2006) 11–27).
First note that a "supercapacitor" is a capacitor in much the same way that an electrolytic capacitor is a capacitor, and differentiating them as you have is somewhat problematic--you should be specifying what that other capacitor type is.
Also, and this is really more nit-picking on my part, but if you want to differentiate then you should note that "supercapacitor" is actually a brand name. A better descriptor would be "electrochemical double layer capacitor" or EDLC.
Those points out of the way, an EDLC is technically 2 capacitors (electrodes) with a resistor (electrolyte) in series between them. There is no set value for charge times, since the nature of the EDLC and the relative sizes of the capacitors and the internal resistance are what will limit the charge time (things like pseudo-capacitance complicate this further).
As Jacob Ketter. Also,
1) the experimental EIS spectra under different operating conditions (temperature range, SOC, etc.) or
2) EIS spectra data shown in their manufacturers' specs
will give you a good hint for the specific Freq. range (Frange) used in your applications.
What is the Frange of (your) interest ?
Surely, the charge times depend on the capacitance of the capacitor (makes no significant difference what kind of capacitor), the voltage you intent to charge it to, and the voltage and current available from the source of this charge.

The current is taken into account, in the above link, by the voltage of the source and the series resistance R. Set up that way, using a voltage source as opposed to a current source, the charging current will vary over time, reducing as a negative exponential, until the capacitor voltage = the power supply voltage (theoretically, it will ever quite reach that value).
Conceivably, you could instead assume a current source, where constant current flows to charge the capacitor, and then is stopped when the capacitor voltage reaches a certain desired level.
This is a question related to the definition. In my opinion, capacitor is faster than supercap, assume supercap is made of carbon material while metal for cap. However, supercap has higher capacitance than cap. That is why it can be called as supercap.
Yes, surely[1], it is so, in theory[2], for the ideal capacitors.
However, for the case of the recent real "supercapacitors" the(ir) nominal (high DC-)capacitance value (CDC) depends on the Frequency, strongly; their, actual CDC, value reduces a lot (many orders) at medium[3] (and reduces more at higher) Freq. ranges.

Ioannis, the disconnect might be in how we interpret the question.

The question implies a DC charging voltage, or Neil would not have asked how much time it takes to charge the capacitor, no? If you feed AC to the capacitor, especially the higher frequencies, it will never reach full charge. Instead, it would charge and discharge, then recharge in opposite polarity.
Aren't super capacitors typically used instead of backup batteries? In that role, AC is out of the question.
(Parenthetically, electrolytic capacitors also change characteristics at high frequencies, where they start behaving more like resistors. When I'm feeling obsessive, I prefer to connect a metal cap in parallel with each power supply electrolytic cap, to be sure to filter out any RF noise there might be in the power distribution wiring.)
