I find jods really comfortable becuase of the way they fit - the seams are obviously made for riding, but also there are no random bits of fabric to get bunched up or caught or twisted. It's just ... easier to move in them. For example, I'm wearing jeans right now, and if I cross one leg over the other the fabric moves and bunches along the inseam and where leg meets hip. I don't get that in jodhpurs.
I only own two pairs of jods, but the people I know who ride every day and all have loads. They have good pairs and casual pairs that get worn for mucking out and casual riding and end up filthy xD I have a pair of navy and blue jodhpurs, which are nice, and a pair of pink-white-green-blue-orange candy-coloured pinstripe ones which everyone admires
