Bell Vs. Rogers - thoughts on stability (not only price)

hi Guys,

since Covid started, my internet at home has been rather spotty,
services like zoom have been extremely flaky (and not for anyone else on the meeting) as well as often times i would have very slow services like youtube on my tv. I think this is mostly due to my rogers internet service (and not within my home) as its often during working hours only and then the rest of the day its fine. (my wife is also at home vpn'ing to work and my kids are probably on one or two tvs using youtube/netflix regularly)

I have rogers 1gb plan and normally its quite good but i can't deal with the consistent zoom issues so am thinkig to switch to bell.
Would this really make the service more stable? i know bell fibe (which i am good to have) is not supposed to be ''shared" but is that just a marketing talking point or is that the reason why my service is spotty?

My home router and network is pretty good (mostly wired) so i know its my issue.

thanks
