I think that pretty much covers all of the Outemu-branded silent switches. Of course, there are also various Gazzew branded switches made by Outemu, that others have already mentioned.
@Deadeye already mentioned how the V2s are just revisions of the same line, and the Jade and Cream Yellows seem to also be in the same revision family as well. I’m not sure if the “Lime” is actually a different switch than the “Lemon”. I think it just might possibly be a case of inconsistent naming practices across different resellers, and these might just refer to the same thing as the “Lemons”.
I’ve tried all of those Outemu switches that you’ve listed. Since they are relatively cheap and it’s possible to get a 27-switch sample pack from INEDA Digital Store on AliExpress that has all of those options (well at least one of each revision line) alongside several other switches that Outemu makes. The sample pack is only $9.01 right now and it’s what I bought to try these. Note: you may have to click on an option selection after visiting this link to specifically select the 27-switch pack.
By the way, out of all these and many other silent tactiles that I tried, I wound up liking the Outemu Jade Yellows the most, closely followed by Akko Silent Penguins. I also think that the Wuque Studio Silent Tactiles and Haimu Whispers are good switches, but they are somewhat louder and hence represent a different point of the quietness-crispness tradeoff curve.
