Well, it's not particularly surprising that they end up producing a lot of similar content - even beyond what is sponsored by EA - since they cater to a very specific audience with highly niche interests. Even more so if they're also friends and frequently exchange thoughts and ideas with one another. But, all that aside, I'd say their opinions are mostly their own, which is why even when the content type is the same, their opinions tend to vary quite a lot, with Plumbella and LilSimsie becoming ever more critical (one of gameplay and the other of the build quality), and Deli & Turner more focused on the quality of build items (although I think Turner enjoys Planet Zoo more than he's been enjoying TS lately, bu that's just me speculating). Sure, the content may frequently be sponsored, but since they're clearly not forced to share the same opinions, I don't really see the problem.
Also, it's not very surprising (or suspicious) that they will always try to be constructive about their criticisms since .. well ... it's their livelihood. Not working for EA, but being YouTubers whose careers - at least for now and for most of them - kinda stands and falls with the sims. So I can 100% understand that they prefer not to be cut off from things like early access. Doesn't make them sellouts, just people trying to make a decent living. I actually think some of them would probably do well expanding their horizon to other gaming communities - at least the ones that are becoming more and more critical and dissatisfied - since they may end up not even wanting to create content for TS at all, which given that 90% of their audience are simmers ... might not be ideal. But that's another discussion of course :)
