Good points, that's for sure.

I would say the smaller dragons would never engage in combat for a simple reason; the costs are much higher for them. It takes a lot of work (unless we are going to say the Skrill could fry a larger dragon's nervous system) for any of the smaller dragons to get any of the larger dragons vulnerable enough to kill. The fight with the Red Death certainly shows that. The main problem with the smaller dragons is it only takes ONE hit from one of the larger dragons to take them out for good. So... Toothless can pepper the bigger dragon, get it angry, punch holes in its wings, and then maybe even eventually get a kill shot, but he would never try that because it only takes one bite or one shot from the bigger dragon to wipe him out. Sure, he's fast and can dodge, but none of the smaller dragons would ever be stupid enough to take the risks. Chances are they could hurt the larger creautures, but they would lose their lives in the process! Toothless is smart, so his victories always pretty much depend on his brain power, not his physical advantages (he does have advantages, but in both cases where he has defeated a very formidable openent [like the Skrill and Red Death] he has had to use desperate strategies, never a flat out fight). Of considering we only see one Night Fury, and that Night Fury is Toothless, we can't really know what he would be like without Hiccup. Better or worse? I'd honestly say better in some ways, and much less good in others...

So, in that sense, the larger dragons are more powerful, but if it comes to a question of who would win a flat out battel, then all the variable really are what detirmine everything. As in the movie, if everything goes absolutely perfect Toothless can kill one of the larger dragons, but he has to have everything play in his favor for that to work. He still wins, but as always with small, fast, smart character, they only win by the skin of their teeth.

Although the Skrill being able to direct lighting does make me curious as to how affective it would be against a larger creature. Armor won't be of much use if your nervous system is destroyed.
