3 was the first one I ever played (after Oblivion tho to your beth point) and it was so radically different from anything I played before that I just fell in love.

New Vegas didn’t capture that same feeling in me, I like it but it just didn’t hit me the same way.

Fallout 4 I enjoyed a ton because of the base building and refinements on scrap usage for modifications and such, with mods like Sim Settlements it can be so damn cool.
