FO76 had a rocky start for sure, but they have made a ton of updates. It is easily better then Starfield now. If you compared them release to release then FO76 would be worse, but I think they are comparing current state.
Fallout 76 is a lot better than what it was at launch but it’s still nowhere near close to Starfield. It’s a weird mesh of ideas that don’t really fit together but are still enjoyable separately.
Personally, hard disagree. I don’t find FO76 fun at all. The world feels small, the characters are boring, and finding zany houses sprinkled around breaks any versimility of the world, which is the cornerstone of Bethesda’s games.
I think the houses fit in the world, but the world is definitely small. I still enjoyed my time in it a lot more than my time in Starfield, which is mostly open fields with the occasional settlement/work site/lab dropped in. I don’t think Starfield is a bad game, just not an exciting one.
