20A is fine, max draw with an 11in prop is about 15A. You'll hover with 2 or 3 A (per motor).  Buying a larger ESC doesn't hurt you at all but in this case the 20A is safe.

I got the 20A one by mistake, and it worked fine up to using 11" prop.  When using the 12" prop, it was a bit unstable.

I would buy the 30 A because

(1) there can be large surge currents with multirotors and headroom is good, runs cooler, more reliable  

(2) there will only be a few grams extra weight and similar cost.

(3) 30 A will be more versatile for later builds.

You could consider buying ESC’s that are capable of taking Simon K firmware.  There is a Google spreadsheet somewhere that lists Simon K compatible esc

ok thank you for your help, so it doesn't matter which one I buy, both are useful for this motor, aren't they?
