#2 is the same Y-connector as #1, only with a pigtail.
In either scenario you'll end up with one male fitting and one female, for a pair of 2 panels.
I don't see much sense in #2 (unless they are cheaper than #1), as you'll probably need several feet long MC4 #10 extension cable anyway.
Make sure they are MC4 Y, because occasionally there are other Y-s sold in solar stores (both kinds, i.e. with and without tail).
11A current is high enough to check V-drop as well. Might need MC4 #8 extension from Y to controller, - not #10. Depends on cable length.
