Siphai is an excellant UU. If you're leading in Science(which with the scientific trait isn't too hard to do) you can be leading Siphai against Musketman. Then against Rifleman, and only when it gets to Infantry is it at a clear disadvantage. Though it is 20 shields extra having an 8/3/3 unit possibly before your enemys even have a 4/6 defensive unit is a great bonus. I've yet to lose one attacking Musketman, even against size 12 citys.

Edit-Also, the early Industrial age is a nice bonus, and if you wait to attack with them you can time it around when you get factorys, using your GA to build them more quickly and set up your infrastructure far quicker.
