Dude, I would never put the Ewok movies or the Holiday special above any canon entry. You should know me better. And I rank TLJ at least as high as TPM.
However, there is something true in what you wrote: if you don’t like R1, don’t bother watching Solo which is “less good” (or “worse”, depends ont the point of view).
Solo is better than RO, though the idea that if you don’t like one you won’t like the other is probably true.
