I might be wrong, but my perception is that there are a few die-hard Siglent fans here, a couple of Siglent distributors and another two or three Siglent testers.
They go around the forum, especially Rigol threads continuously, showing how $3k scopes are better in every regard than $300 ones, and there is even a $400 Siglent scope that is
much better at FFT than Rigol.
There are surely die-hard Rigol fans, but they aren't as active. You can identify pretty clearly who I'm talking about, because they only show specific things that are better on Siglent, and never anything that's better on Rigol. They are also really active in the forum and, besides their (nonprofit?) Siglent PR and advertisement work, they are competent engineers, useful contributors and, most of them, quite nice actually.
EDIT: They sometimes aren't as nice, if you dare to criticize Siglent. They might even be capable of questioning the professional competence of some users if they dare to chose a cheaper Rigol over Siglent for hobby use, which nobody competent enough would do
I think every hobbyist has to thank Rigol for driving a very strong competition, pushing the rest of manufacturers to compete in price and features, and also has to thank Siglent, for bringing refined software and higher-end analytical features to the entry level TM market.
I sometimes get "sports team fan" vibes from the arguments about Siglent vs Rigol. Again, I might be wrong, but hardly biased.
