I would propose
MegaBlast,
Karous(easy) and
Night Raid as games in which players can virtually avoid dodging bullets simply by positioning themselves in safe spots or by destroying all enemies before they can shoot.
On the Japanese difficulty wiki: my understanding is that they used a scoring system similar to the one for the "top shmups" on this forum. However, the voting conditions were a bit of a mystery, at least when I read the Japanese page via automatic translation.
Participants voted games with scores from 0 to 50 (i.e. via a
Likert Scale.), and possibly didn't have to motivate their grades at all (so, no information on
why and
how they offered their scores).
Likert Scales can quantify general opinions, but usually in a coarse-grained manner.
If 50 people vote, and 40 people vote that
Ketsui is easy (e.g. 10/50 score), but 10 say that it is supremely hard (i.e. 50/50 score), the average value is (10*40)+(50*10)=18/50 (below average).
If the 40 people voting "10" are from the "Ketsui 2-ALL membership club" and the 10 people voting "50" are "everyone else", you can see how the final score *might* be a bit biased. More in general, flattening every opinion into a "collective number-based consensus" can create deeply unintuitive results.
Ketsui 1-ALL is listed at 21/50, so I guess that I *might* be not too far off the track.
So, the wiki seems to offer the coarse-grained opinions of some Japanese players, based on apparently completely opaque parameters (but at times clearly bizarre, I'd add).
The other issue is how representative the Wiki is. The "top shmups" thread featured 71 voters out of 22231 members of this forum, which is roughly 0.003% of the total "population". The Wiki difficulty poll...beats me.
I wouldn't consider the wiki or the poll particularly representative of anything, to be fair (sample too small/sample unknown), but they can give a first sketch of their own domains of inquiry, perhaps.
Titles can be misleading, of course. Then again, we live in an epoch of endless click-baits, to the effect that newspapers have all turned into sensationalistic penny dreadfuls, more or less.
"Git gud" and games will become easy for you, bit by bit.
Maybe.
