The test was odd. Essentially because I prefer water it placed me there. Either way, I don't mind.
Personally I enjoyed Draco's redemption story throughout the entire series. And then there was Snape as well. Complicated people. Much more interesting than a lot of Gryffindors. I mean if you want terrible Gryffindors we have Percy Weasley. Turned his back on his family.
The problem with the test and the books with regards to houses is that even though I think I should have been Ravenclaw, Rowling never fleshed out Hufflepuff or Ravenclaw properly. So we don't have enough of them to see what they are truly like. I think I did the calculations once that there are roughly 40 people per class at Hogwarts - so about 280 people in the school - and Rowling just never felt the need to tell a story other than through the eyes of Gryffindor and their antagonists Slytherin. She would have done better to make a more nuanced story that showed evil/good people from all the houses rather than the clear only good/only evil duality she had going on. But this did begin as a story for children before progressing into what it became in later books.
Do I think any one of the houses is the best? Clearly not. And that kind of chauvinistic attitude is really so old school. Reactionary even. Looks like you should be happy you're in Gryffindor. But you sound like you could have placed in Slytherin too.
BTW - you forgot Harry's son who placed into Slytherin - Albus Severus Potter.
P.S. What do you have against using the word 'Philosopher' with its medieval alchemist connotations? A sorcerer is not a person of intellect.
P. P. S. - you seem to have gone to a lot of trouble to try to justify your so-called Gryffindorness. You sure you didn't get placed into Hufflepuff? You can always do the test again if you need to feel better.
