Standard snow pants are still a great choice for a lot of riders, especially if you mostly stick to resort skiing in mild to normal conditions. They're simpler, lighter, and way easier to deal with when you need a bathroom break—no straps or zippers to fuss with. If you run warm or like to layer underneath, standard pants also breathe better since you don't have that extra chest coverage trapping heat.
The main trade-off is snow protection. If you're charging through deep powder or you fall a lot (no judgment!), snow can sneak in at the waist and leave you cold and wet. Bibs solve that problem with full coverage that seals out snow. But if you're mostly cruising groomers, skiing on warmer days, or just prefer a more traditional feel, standard pants get the job done without the extra bulk.
