i think it depends on conditions. i had studded tires on my mtb and rode on the maybe twice but just like studs on a car they didnt help much in deep loose snow. the rope was a diy i had to do. here's the story: friday was expected snowstorm in the afternoon. fearing i wouldnt be able to get home from work in my mini cooper, i opted to ebike in. that way i could stay off the road and away from traffic. problem was ice! i had one 2.5" knobby tire and put it on the rear (mistake#1) and didnt let enough air out of the front (mistake #2), didnt watch for black ice (mistake #3), fell hard and broke my helmet and bruised some ribs. during the day at work i had to figure something out to get home. lookedat zip ties but they seemed too thin so i got the cord at rite aid at lunch and let a lot more air out of the front ~20 psi. those two fixes plus new snow on top of the ice made for a very nice ride after that! i also got more dialed in how to ride in the snow, putting a foot down near the ground when the bike gets squirrely saved me a few times too. i'd say with the conditions we have now ie. deep snow, the rope is a far better option and it only cost $5. live and learn!
