As a serial jeans wearer, the only way to know is to try them on I think, because every brand, and every style is different, you need to hone it down to what shape of jeans you are looking for, and what fits and suits you best.
I’d start at M&S, which has a huge selection, to work out exactly what you prefer before you hone your search down to eg high waisted, barrel leg, dark indigo, regular length - or whatever, then look for jeans from other companies which meet your criteria.
Maybe controversial, but also try some without stretch, I prefer them as they hang better, and hold their shape as long as they aren’t too tight over your knees.
