Wingo vs Classic Swisscom

I want to change to Swisscom because with other providers I do not really have good reception especially at home. With my employer I could get a Swisscom subscription for a cheaper price. For ~CHF 30 I could get everything unlimited within Switzerland but without any included roaming data. With Wingo I could get the same but with an additional 6GB of roaming data for just CHF 28.95 so I am considering just using Wingo instead as it is also using the Swisscom network.

Is Wingo in anyway worse than a classical Swisscom subscription especially in regards to reception, coverage and speed. Maybe anyone has experience? I could think of things like de-prioritizing Wingo customers in case of huge traffic load during rush hour or something like that. If that would be the case I would much rather pay a few bucks more and maybe setup an eSim if I'd need to travel.
