Hope this upload works.
So depending how many batteries you end up with or how you want to use the charger, there are some differences. For a single battery, Dynamite C3010 is pretty darn good for the money. The Dynamite C2050 beats a CellPro PL6 running at 300 watts while doing (4) batteries, but if you are just charging (1) battery the C2050 cannot keep up. This doesn't cover all your options, but most options will fit close enough to this table. If you have lots of time and wanted to do a lot of flying, the PL6 at around 1000 watts could keep you in the air all day assuming you could handle it
If you wanted to venture above 1C for the 6S 10,000 mah batteries you are going to need at least 600 watts of power, so I just noted it all at 1C.
I included some other popular batteries for anyone else looking as long as I was doing it. As you can see, spending more money doesn't help everywhere and this applies to each case.
If someone has a question or I made a mistake, PM me. I had just tried to clean up and make relevant a previous table from when I was debating chargers.
