Both the above are generally right, but I will explain further and hopefully answer your question in more detail, as I am assuming you are looking to buy a kite and the answer is important:
SLE's and bows are generally similar as you have noted and are flat with a swept back shape compared to a C. As mentioned Bows have a concave trailing edge (TE). I understand this is subject to a patent, and you can't call a kite a Bow if has a straight edge, which many SLE's do. The term SLE was coined by manufacturers to describe thier new bridles kites, that may or may not confirm to the patented Bow specifications. SLE's have bridles, and are best known for their safety through the vast improvements in bar release depower available on them. This also gives them a larger wind range compared to C's. Most if not all instructors/schools use SLE's due to their stability and safety.
Hybrids I believe are a mix of C and Bow/SLE type shapes, trying to bring the best of both into one kite. I don't think you could say a hybrid is just an SLE with no bridle, as they definitely have a less swept shape and have more of a deeper C arc to them - due to no bridle support. Therefore they really are more of a "hybrid"
I fly Airush kites and I simply think of the following:
Flow: SLE (obvious with bridle)
Generator: C
Vapor: Hybrid
Pretty easy to see the difference if you check them out on their website. None of their current kites could be called a Bow.
