Edit: I’m used to subtitles. In the same language, in another language, even in two other languages at the same time. One reads them unconsciously, a few minutes later maybe one can’t even recall if there were subtitles or not. But when you’re reading them, even if it’s just a fraction of the time, you’re not looking at the whole picture. Comparing them to the network logo is ridiculous.
Another phenomenon is that, due to the sheer amount of Japanese drama/anime I have watched with English subtitles, I can often spot translations that are unidiomatic, even though I have no formal training in the Japanese language.
The only annoying thing could be bad subtitles, as in the translation is poor and you notice it. And of course jokes that don’t work in Swedish get lost or changed in translation, which you notice in the subtitles. These situations happen maybe once, for five seconds. Far less annoying than not even hearing the actors’ performance.
Regarding the « no difference whatsoever », you noted in a previous comment that you know a few seconds in advance what’s going to be said.
Yes, sometimes that will affect the drama of the scene since the pacing of information in the scene might be compromised. That's likely to happen with dubbing too, because the grammar doesn't match and a name has to be mentioned at the beginning of the sentence in one language instead of the end, as the director intended. Since Swedish and English are both Germanic languages it doesn't happen that often in the few movies that are dubbed to Swedish, but I've seen it get really weird in Swedish films dubbed to Spanish.
Either way, in my experience, if I see Clint Eastwood's line a moment before he says it, I can still feel the scorching sun and smell the gunpowder like I'm there in the old American west. That atmosphere disappears completely when I hear his line in German or French.
“There was a crude “guide track” recording what was spoken, but often Leone lost or ignored this guide track and when the time came to loop the dialogue, frequently no one could remember who had said what. Eastwood recalls being warned to keep his OWN NOTES about what he said in each scene, and sure enough, when he was called on to loop the two Dollar movies, production had lost the guide track. They had NO IDEA what Clint had actually said in each scene and Clint had to re-record them as best he could remember. (Another reason why his lip movements don’t entirely match up.)“
Reduction of atmosphere is just one of the reasons I don't like dubbing, the fact that it robs the actor of his or her oral performance is the major one. But there are more reasons, many of them I've already mentioned such as mismatch in grammar leading to changes in the dramatic pacing.
