That's not really your point, though - your point seems to be that everyone could make more character concepts with 3.5 than they will be able to with 5.24. Now, leaving aside that we don't really entirely know what we'll be able to make with 5.24, I think it's a bold claim, and I think you're going to get a lot of pushback. In particular, when the designers, who probably ought to know, have claimed otherwise.
(And taking into account that you seem to be discounting any 5e builds that you couldn't build with 3.5 and only focussing on builds that you DID build in 3.5 that you can't, for whatever reason, in 5e.)
I admit that I am not anywhere near as impressed with 3.5 as you are, but I don't really have any skin in this game. As unbiased as I can try to be: I still think you're mistaken, and seeing 3.5 through rose-tinted glasses. (I'm glad you liked it, though! It was a very popular version of D&D, you're in good company, I'm sure!)
