Have you played newest entries?
They are hard to play because they lack a lot of QOL stuff and one big motivation to play them is nostalgia.
If you are open minded and want to visit them for the history go ahead, if you think you could invest your time in something better then don't.
I finished Pokémon Yellow recently but for me it was easier because I played Pokémon Red in its day, and this time I used a Miyoo Mini which has some perks on its own, like fast forward, rewind, save states and fast shutdown and quick resume (basically all good things emulators have but on the go) I could say I abused of FF except to listen its great OST, also there are the GBA remakes which improve them a lot... so there are my two cents 😀
