If I had to produce a build today ... and assuming the grouping represents all cards fitting "within budget", the 2060 is obvious ... its the fastest among the bunch with all cards overclocked
MSI's Radeon RX 5600 XT Gaming Series comes in two flavors: the Gaming X and the Gaming Z, which has higher memory clocks. We compare both cards and their massive triple-slot thermal solution that achieves amazing temperatures and noise levels. Fan-stop is included, too.

Using the 2060 Reference card as baseline and TPU overclocking data and MSI test results except where unavailable
Reference RTX 2060 = 103 % / 103 %
MSI RX 5600 XT Gaming Z = 105% / 103% x 93.9 / 90.2 OC = 106.12%
Powercolor RX 5700 Red Dragon = 112% / 103% x 103% / 102 % OC = 109.80
MSI RTX 2060 Gaming Z = 103 % / 103 % x 121.1 / 107.9 = 115.60
MSI GTX 1660 Super Gaming X = 86 % / 103 % x 94.3 / 83.7 OC = 93.67
OK let's now factor in price of new system, again baseline = new system with MSI RX 5600 XT Gaming will be our baseline at $1200 ... ... and we've seen that from TPU and other reviews reviews that the Performance of the Gaming, Gaming X and Gaming Z are virtually identical ... the X even being insignificantly faster in 5600 XT testing. For the most part, they are identical cards with different overclocks ... The only thing we have to check is if they have the same memory. In the case of the 5600 XT, the Gaming Z has 14 GBps memory, the Gaming Z does not. While a price premium here would seem to be warranted for the Z, again, the Z is actually slowe in TPU testing. For the 2060, the Gaming and Gaming Z have the same 14 GBps memory.
MSI RX 5600 XT = $333.98
Powercolor RX 5700 Red Dragon = $359.99 adds (+$26.01) to our $1200 build
MSI RTX 2060 Gaming = $275.99 (subtracts (-57.99) from our $1200 build
MSI GTX 1660 Super Gaming X = $259.99 subtracts (-73.99) from our $1200 build
MSI RTX 2060 Gaming = 115.60 x 100 / $1,142.01 = 10.12
Powercolor RX 5700 Red Dragon = 109.80 x 100 / $1,173.99 = 9.35
MSI RX 5600 XT Gaming X = 106.12% x 100 / $1,200 = 8.84
MSI GTX 1660 Super Gaming X = 93.67x 100 / $,1126.01 = 8.31
So out of the cards listed, I'd be looking at a MSI Gaming 2060 or a comparable priced card from one of the other AIB vendor's top model series.
Unfortunately it is impossible to find tested cards for ever vendor and ever model. It should be obvious however that the same PCBs are used across many model lines with each AIB provider; the main differences are coolers, factory OCs and memory. As we was saw in the 5600 XT testing, the better memory actually produced lower overclocked performance. In addition, since the baseline for pricing was the 5600 XT, I tried to use MSI across the board, except when TPU did no testing. There is no reason to dismiss other AIB cards which you might find that are lower cost ... but keep the comparisons comparable ... Asus Strix line, Gigabyte Windforce, etc. Check TPU testing when available.
And yes, there is a bit of bias inherent to the source material
-The 5600 XT Gaming Z and Gaming with different memory have virtualy the same performance .... so used the cheaper X version in pricing
-The 2060 Gaming Z and Gaming use the exact same memory, with only **physical** difference being the factory OC

The power consumption is unimportant. If you worry about that you should not buy a PC at all.
1. All other things being equal, why not ? I mean if ya parents pay the bill ... or your electricity is included in the rent, I can agree. But the power savings over 4 years can almost pay for the purchase cost. Not as much of an issue at the low and middle range, but at the high end, it's certainly significant.
At the high end, differences in performance can be 100 watts or more ... over 4 years, I'll spend $178 more on electricity playing 30 hours a week
2. Using the (1) 120mm fan for every 50-75 watts of power draw rule of thumb (75 - 100 watts for 140mm), that means adding an extra case fan to compensate ... + $10 - $30, say $20
3. Adding 100 watts to the cost of a decent power supply, you're talking $10-$20, say $15
So... if $213 ($178 + $15 + $20) is insignificant, then giving and edge to a lower performing card because of price is counterintuitive defying any sense of logic.
