#1 with studs , if you will be driving on icy hills definitely no competitor will be around.. with the drawback of them being really noisy (and a feeling of disturbance on steering) on dry and wet but much much better than any kind of chain..
#2, definitely ice, snow tire..I would buy that.. but will limit your speed and handling on dry/wet roads .. imo no need for more than 60-70 mph in winter..however also you can use a combination of #2 at the rear (for omega) and #3 on the front ..
#3 snow performance tire (can be also used for ice but dont expect performance like #1 and #2) and can be used for higher speeds even in dry/wet
I must note all of these comments depends on the assumption that all of tires have the same compound quality ..
one last thing to add: tires especially designed for ice have very soft compounds ..
try a simple test.. take the tires outside one by one, push from up with all your weight and try turn them left right which turns harder is the best for winter.. (studded being exception)
ps: a combination of #1 at the rear and #3 also can be considered..so studs wont effect steering..
pps: now I see, if those tires are for rav 4 all 4 tires must be equal..
