I know Bakshi's version has A LOT of issues, but I grew up watching it again and again and I have very fond memories of it. I'm aware I am in the minority.
One of the scenes I love is Boromir's death (video link)... if you can ignore the "not-enough-budget" Uruk-hai. I like the roughness and lack of music once Boromir's is hit with the first arrow.

Well it's just a surprise. I'm sooooo used the Jackson version. Love it to death. But it generated a lot of fantasy tropes that Hollywood is finding difficulty to depart from.
For example Legolas in this (while butt-fucking ugly) shows concern and genuine shock whereas elves in the Jackson films are generally stoic. Like "that's disappointing, one less sword to swing st our side. Well tallyho chaps we have work to do."
I just find the dichotomy interesting, I do revere Jackson's work as masterpieces of cinema.
It's a matter of taste, so no one is wrong here.
That's a hard one. I don't have a strong opinion about each take. Legolas is not one of the best characters on Bakshi's film, and I don't remember enough about the book to say which one is more faithfull (if that's something you appreciate).
Just to be clear: I think Jackson's films are incomparably better product than Bakshi's, they are not on the same league. 1978 version is not even finished! The only way you could compare them is by factoring their bugdets. But I don't know how to "divide my opinions by a number", hehe.
I like having both so people can choose, or watch both.
