#2 all the way. 1,3,4 all have weak peduncle and will show significant tail droop at adult size. 2 looks like it has the most head potential although it has a female spot in the dorsal. It could be just be a marking from the partial double row.
#1 imo -- a bit different looking due to flowerline and also has the best coloring around the face/mouth -- others might have different experience, but ime no matter how red the rest of their body may get, the coloring around their face (esp. front & center) and mouth changes little if at all.
